Definitely not true. Ran the test at a local BestBuy on a 27 incher. Perfect.
My week 50 is yellow as well.
Although the backlight bleed is a little better than the last so I may keep it.
I really think that all of them have yellowing to some degree.
Oh well I guess I'll keep this one until Apple straightens things out then I guess I'll go the repair route.

Lol, first rev will always be first rev. 
I just got off the phone with apple
THey know about the issue and are recommending the repair route.
The production runs will still have the issue until they roll the fix into production.
He said the repaired unit will not be returned with the same issue.
They will put in a display that they know is good, not what comes off the line.
So I will keep mine and wait until after the holidays to get the repair done.

Good to know! If it weren't for the isight and blown speaker, I wouldn't even be typing this at the mall as I wait for my genius..
I'm VERY glad Apple is acknowledging this and taking it seriously. Really, REALLY big win. I wish that this info would filter though, since the dudes I talked to today (though native English speakers - one Ozzy and one fellow Yank) seemed to think that the yellow tinge was a very rare problem and they believed it to be just a defect, and not widespread, as they had only heard one or two calls about it.
Wow, great news, thanks for sharing! I am calling tomorrow as I have an issue with a loud vibration & hum that will most likely require a new machine, I will attempt to inquire when they estimated the "good" screens will be put into production... Interesting that they mention it is the screen, another post mentioned that the apple rep stated pretty confidently that it is a graphics card issue...
Be wary - they may very tell you that it is within spec and not replace the screen. I would get that in writing.

I have been struggling to see any difference and Ive asked other people who might have better eyes than myself but I see no difference. Is there another, a better test graphic? I would imagine the back lighting would make a difference, Ill try it tomorrow in the day light.
My iMac came 11th either I'm very lucky or too blind to see any real difference.

Well, that was a giant waste of time...
Spent two hours at the Apple store tonight, after having been told both by the "senior" applecare rep I spoke with AND a girl from the store that they carried the i7 in the store... only to find that, surprise surprise, they DONT CARRY THE GODDAMN i7 IN THE STORE. Why oh why do I bother listening to any of them when I KNOW that what I KNOW is right? Ugh. The genius did actually acknowledge my issues, though she said that several dead pixels in the iSight was not enough to replace the camera, and she hemmed and hawed over the screen test, and tried to tell me that viewing angle was solely responsible. Riiight. Try looking at it dead on. It's THERE.
In the end, she told me to call customer relations and have them advance me a new computer. Great. Thanks. Can I have my two hours back now? *sigh*

So my 27" i7 iMac just arrived. I turned on iTunes visualizer (full screen) and let that go for about three hours. Also checked out the yellow hue/tint test. My machine apparently has no problems as of yet (serial number indicates week 50 build). I will see what happens over the next week, but so far, an amazing machine.
I wouldn't be surprised if some of these people have been planted here, put here by Apple's competition to stir up hysteria.
Look at this fellow's handle for a start – 09iMac=Fail. And just joined Macrumors too. He's probably having a good laugh with his Microsoft pals this very minute. A lot cheaper than running an anti-iMac ad campaign.
And this is from the VERY FIRST POST OF THIS THREAD, urging you to do the test:
"Warning: Do Not Tilt the Angle. If you do tilt the screen upwards, the yellow will fade — BUT as this happens, the top of the screen turns Purple, which will be more difficult to notice in grey."
Well, we wouldn't want the yellow to fade from view. Or for the purple to be difficult to notice, would we? Why don't we all start doing a poll on the purple tinge too?
I am not sure what exactly are you trying to say here. What I wrote means what it means in its exact words. There is clearly a color gradient on the display that's not suppose to be there. Nobody will ever see the purple if you are looking straight at the computer. However, the yellow is not suppose to be there when looking at it straight. Sitting side by side with other yellow free Apple displays makes the issue look obvious.
The test was designed merely to make the issue easier to spot. The issue is actually very easy to spot (of course I noticed the fault before making the test itself).
Actually if you really wanted to, you can test for the issue just using your Finder or Safari window as some members have pointed out.
If you feel that you can help improve the test please by all means let me know.
Have you done the obvious thing and checked that this issue is not just a very slight superficial discoloration on the lower portion of some people's glass?
I mean to say, if a pair of glasses gives everything I see a yellow tinge, I don't automatically assume the world is at fault and the glass is fine.
Just saying.
Why not remove your iMac's glass and conduct a test on it? And I'm sure everyone here would be interested to know if your test method shows screen yellowing with the glass removed.

About a fourth way down, 3 inches or so.
Hi,
I recently received a W49 replacement for my tinted w46 i5.
It´s much much better with almost no visible clouding. Not perfect but definitely a keeper. Keep the faith. There are good ones out there. But I´d definitely recommend going through the motions with an exchange. These are not cheap computers so the buyer should insist on a quality product especially when the screen is being touted the way it is by Apple.
Good luck!

Don't bother.
The first general argument from apologists was that those problems are very rare (some even went so far to claim they didn't exist and it was make believe). But when different people had different swaps with still the same problem they dropped that one.
The second general argument was that this is normal for a line that isn't targeted for "professionals". Yes displaying white as white on the top and bottom of a screen is a "pro" feature. They also make the comparison with cheap TN panels to prove that color inconsistency its not only limited to the 27" imac screen. Which doesn't make sense.
They dropped that one when people pointed them to the imac pages where Apple literaly states
http://www.apple.com/imac/features.html
And Apple is right, a GOOD (!) LED IPS panel would display colors consistent. White at the top and yellow at the bottom I personally wouldn't call consistent. But then maybe some people have a different interpretation for the word consistent.
Now the new (very amusing) argument seems to be that it's one big conspiracy... . I wonder how they planted that 27" imac that I saw in the mediamarkt that also had the yellow tinge problem. There seem to be a lot of people involved in it.
Just called apple last night. Mine 50 week i7 27" got yellow tinge on bottom right. So I decided to exchange it last night. Apple agrees to take it back without asking me to proof anything. I just mention mine got uneven color tone accross the screen. They offer me 3 options.
1. Full refund with fedex sticker for free shipping return.
Which is no good for me, because I got black Friday deal. Next time I buy will be without discount.
2. Ship it back with free shipping label within 14 days. Then they sent new one when they receives. They claim they have new batches without issues waiting to be shipped out now. Will be imacless for one week or so.
3. Bill me for another one on credit card. Sent new iMac out. Then return the defect one when receives new unit.
I picked #2 let's see how it goes. I order online through apple online store.

Maybe treat that statement with a rather large pinch of salt. Not saying you won't get lucky but I have major doubts they have apparently resolved the "issue". Incidentally, when I got my iMac exchanged (loud HDD) they allowed me to keep the old one until I received the replacement with no charge to a credit card so I would push for that if I were you - it is possible.
I just spoke with an Apple Care Rep, and got bumped up to a Senior Advisor.. I stated to him a few times that I would rather get a refund and purchase a new iMac once the yellow tint issue is resolved.. He was VERY careful with what he said, but he hinted that they are aware of the issue, and I SHOULD NOT have the issue with my replacement machine.. I told him outright that I know that Apple is aware of the issue, but if the machines that are still in production do not have the fix in place, I would rather wait.. He then stated (indirectly) that they do not need my machine for evaluation for the yellow tint, and that my new machine should not have the problem. He was not giving information, but I think he was trying to tell me that they have a handle on the problem and the batch that I get should have the issue resolved.
He did not provide the option of getting the LCD fixed later as I also have a problem with a loud constant hum/vibration from the imac that is probably a bad sensor and they do want the machine back for that.
So, I am looking at an estimated January 5th shipping date (which is interesting as this date is longer than two weeks, I wonder if that is when they anticipate the issue will be resolved??) Just speculation on my part, don't want to get folks fired up here.. I am happy to wait and let them get this stuff sorted out.. In the meantime, I am back to my old but reliable G4 Powerbook for a while... Can't see yellow in that 6 year old screen as it is barely bright enough to make out anything... (-:
On a side note, the customer service was outstanding, and everyone I spoke to was apologetic, professional, and eager to help me out...
