So, it's a Chi Mei display:

Interesting that the contrast ratio and brightness (800:1 and 350cdm2 vs 500:1 and 300cdm2) are both higher than on the other LG and Samsung MBP displays. You'd think that they'd try to keep the characteristics the same. In any case, you should really return it and get a display that is worthy of the beautiful laptop!
To be honest, and I hope I don't make this worse, I think the Chi Mei displays are the worst of the MBP displays. the ones I've seen installed in the SR MBPs have all had a kind of muddy murky yellowish tint and been unable to display pure whites. I'm really amazed that Apple continues to have these issues. It all started with the last generation of powerbooks several years ago which had strange horizontal lines. After that the first generation MBP with very uneven illumination and that graininess that was so hated and now these yellow LCDs. How can this be such a problem? I mean, Apple is using the main suppliers of displays and yet I have yet to see these issues on PC laptops. Weird. End of rant.
Hope you get is sorted quickly - good luck! Apple is usually quick to fix these things, even if they really should have never allowed them to happen in the first place.

Given what you said, I don't think there will be any problems. I would go check the other MBPs first so that if the genius can't see it, you can point them to the other good ones that are on display. Always good to have contrasts. I doubt you'll have any problems, but if you do just talk to the manager as they usually are very good to deal with and will be accommodating.
Unfortunately, I don't think there is any certain answer which display model is better than the other as there seems to be variation even with the same model. The 9c83 seemed very nice when I saw it in the store and a few others on the board have reported the same. It's a Samsung. But I would just look at it carefully both in the store and when you get home in better lighting and not settle for anything that you're not happy with.
Let us know how it goes!

When I went into the local apple store this week, EVERY SR 15.4" Macbook Pro had the yellowing. It was horrible. Luckily my Penryn either doesn't have it, or I just haven't noticed it. Sure the viewing angles are worse making the bottom look darker but if i move my head its better.

Goodbye dell:
Was your screen glossy or Matte?
I'm curious as to whether there's a pattern with this problem being on glossy vs matte screens (I'm sure it's been discussed, but I get depressed the more I read about these problems.... and the more depressed i get, the less I want to order my macbook pro! Heck, I've put it off 4 days already... I'd love to pull the trigger tonight!)

when i was at the store earlier ,played with the display MBP all of which have the Penryn..
some of the sales people doesn't even know how i know the yellow tint test..
i don't know if they're new or what?
but it seems if you're not a follower of this forum..
chances are you don't even know it exist in your machine.
i asked them if ever there's someone who cmes in and says that the screen is a problem.. will they replace it right away?
they said not really, it has to be shipped.. forgot where... nd the people from that department will decide if the yellowing is an " acceptable/tolerable or not"
then they'll either change the screen or ship it back to you..
but never will they exchange it right away..
unless of course the lcd problem is so obvious like dead pixels etc

Just got my new 2.5 penryn mbp today 
.
Did the white test, and I noticed a slight yellowing from very specific viewing angles. But as I moved around more, I could see that the yellow was an artifact of the orientation of the screen in respect to my eyes. I have concluded, in my case, that I have no yellowing problem. As this is my first mpb, I am unable to compare with other versions.
Manufacturer:610
Model: 9c81

i think mine has a very suttle "white-yellow" tint in the bottom 1/4th, but the thing is, it seems to only be on the left half of the bottom 1/4th and it is very suttle i can barely tell when looking at it. I really wish i never ran this test, hopefully its just an optical allusion, but it definetly seems like it has a very suttle white-yellow.
Panel: 9C81

if it's no that much of a bother for you..
i'd recommend not to exchange it..
some get dead pixels etc... it's really trial and error

ya its not a real bad yellow, its really hard to notice, and no im not returning it, im not taking a chance of getting dead pixels.
Its not very bothering as in its not very obvious at all, but just knowing "its there" and something isnt "right" just really sucks lol.
It might be just because of looking at a bright spot for a long time: you also see some shadows after looking at the sun without sunglasses.
I went through several exchanges myself(though i'm not too picky): first MBP(ordered online, basic model) came in the end of January, and it had a dead pixel. No questions asked, got a replacement, opened it in the store - also a dead pixel
The second one was fine, with a beautiful LG screen. It was a nice machine, but (un)fortunately Apple released a new MBP in the last day of my 2-week return period After thinking for a while i decided that the upgrade is worth 200$ and went to the store to test my luck again ^^ I was surprised that they had computers in stock, so i got the new machine immediately. Of course, it had a dead pixel..The second try was successful, 9C81 screen.Now i'm really sorry that i've sold my 2.0 whitebook, i was so happy with it and didn't need anything better. Money don't make you happy
By the way, as i have already mentioned before, all Samsungs(at least 9c68 on C2D) have problems with 32 bit color - just try the color gradient in LCDtest or Photoshop..
Could someone please run SwitchResX on a 9c81 Penryn? Is it right to assume by elimination it is a LG screen
9c83 = Samsung
9c82 = Chi Mei
9c81 = ?
In my local Apple store they had 2 glossy 9c81, a matte 9c83 and a glossy 9c82. All were perfect as to the yellowing issue. I belive the issue is corrected , as it was figured out and implemented in the MBA screens. No discoloration was evident to my naked eye using web pages of white lettering on a black backgound. It was very eazy to see on SR MBPs. There are differences in the screens as to which manufacturer but this is personal preference - whether you like your colours warmer or more saturated.
Now running professional test images may reveal some minor yellowing but to me they where perfect to the naked eye.
Hopes this helps ppl still wondering whether to order or not yet. The page I used to test with - www.dpreview.com - and then scroll down abit.
One last thing ( where did I hear that before ) I noticed that the Penryn MBPs all had great wifi connectivity. Stable and fast speeds when compared to the other notebooks in the store. Maybe they improved wifi connectivity too.

9c81 = LG, I believe... this is what I have on my new Penryn MBP.
I also have the yellow issue, but it is very slight, bottom 1/4 of screen, in the center, corners are ok.
Still trying to decide if I should take back or not... it's one of those things where you have too look for it, and then you definitely notice it.
All these "yellow" notices are actually a relief, because the problem on the previous issue MBPs was VERY apparent...these reports all seem very minor compared to the issues I had with 2 different SR LED MBPs (one bought in June 2007, the other in Feb 2008)...so its looking definitely good.
Try searching for "icc" files on this forum and apply them to your display profile, you might see a marked difference...

I just looked on mine with "fresh" rested eyes and noticed almost instantly... in fact, it looks WORSE now. I'm taking it back to the store for an exchange today!
Yeah, I did run the display calibration tool, made the white's white... guess what? The bottom 1/4 yellow is still very noticeable. I used some of the screen test patterns posted here, and you can definitely see the top of the screen is white, while the bottom is yellowish. I even tried looking up and down at different viewing angles, tilting back the screen, etc. It's still there.
Now, allow me to put on my tin-foil hat for a second...
Anyone else notice that the Default color profile has a decidedly OVERALL yellow tone to it? You need to run the calibration and make your changes. So... I really have to wonder... if perhaps Apple may be aware of the issue on some screens and does this intentionally, to try to disguise it? Just seems a little fishy to me...
The default "Color LCD" profile is all washed out...get hold of some icc files from the folder and try them out...as for the screen, go to the apple store to get it replaced, you seem the only one with a problem of this entity around here...
