My rMBP arrived yesterday.
Took it out of the box today, migrated all my stuff.

rMBP is in perfect conditions, screen is perfect.

Got mine with an LG screen. Seems pretty OK so far.
On a related note, is there an easy way to check for back light bleeding and image persistence? I tried using solid colors as background in a darkened room and it doesn't seem to have any significant bleeding. How does one check for ghosting/burn-in?

Samsung. No ghosting, bleeding or yellowing. Not a pixel out of place, in fact. I've had mine in hand since a week after launch and it still amazes me how gorgeous it is.
use the dark gray desktop background. put a contrasting image on screen (some suggested google search) let it sit for ten minutes, then close the window. if you see a residual image you have burn in.

Got my replacement today. It's an LG and it's still got more of a yellow hue to the screen.
Guess I will play with it longer than the 1 day I did last time and probably return it. I haven't tested the ghosting or anything yet. But you can see in the picture I attached there is a difference for sure from my Mid 2010 MBP.

I'm trying that right now. It's funny cause I get an error that the Default file is not available for this display.
Yeah I calibrated it and still has a yellow tint compared to my iphone as well as my 2010 MBP.
I'll enjoy this for a bit more then return it. Was hoping to have a good one before my trip to asia but I guess I'll just wait till I get back.
hmm my LG has that purplish tint that they're reporting in that thread and it is also considerably dimmer than the iPhone and TB display (all set at max running the same apple.com page)
As I've been trying to explain, the purplish tint is expected and is a side effect of what is otherwise a great feature: The A-TW polarizer. The A-TW polarizer almost completely eliminates IPS glow, so it makes dark scenes in movies (and dark images in general) much more striking. But these polarizers are known to introduce magenta and green hues (magenta from one angle, green from the other. So when you're centered, the corners are at a sharp enough angle).
Here are a couple examples showing the effect. First is a picture dead-center just as a control. Then a sharp angle to show how bad the effect can get. Then a mild angle to show it helps even there.
The monitor with the glow is an IPS display. And until its backlight started dying (it has 13000 hours on it), it had the best picture I've seen of any monitor. But the glow was annoying when trying to watch movies
And here's a picture of an NEC with the a-tw polarizer and an HP without it. Similar difference. The NEC shows the same magenta/green hues
The yellow - I suspect that the LG is closer to 6500K than the Samsung. There have been a few with calibrators that have noted that their LG displays were very close to the intended 6500K white-point. Most consumer products have noticeably higher whitepoints though, so to many, 6500K will appear yellow. There may be some that are quite yellow though. I saw one mention of an LG coming out as almost 5000K
The brightness I think is an IPS vs PLS thing. PLS screens are brighter. But it is also possible that the Samsung doesn't have an A-TW polarizer (though I'm not sure if the film actually effects brightness)
