I read in another thread that people had similar issues down the left hand side, similarly, the 27" iMac I use at work is the same. Is it possible to get a totally, perfect, uniform screen on a consumer device? Has anyone been through the replacement lottery and actually won?
Here is my experience:
The original display (replaced due to dead pixels) on my machine was great. I did not notice ghosting, and whites were indeed white. I do not know what type of display it was.
My second display (replaced due to loose hinge) was also great. I noticed no difference between this first replacement and the original. Again, I am unsure of the manufacturer and model of this display.
My third display was horribly yellow -- to the point where it blows my mind that it left the factory. That being said, it was perfectly uniformly yellow. There was also no backlight bleed or image retention. This display was an SJA2, what I understand to be one of the newer LG displays for the mid 2012 15" retina macbook pros (I am not sure of the number of iterations).
My current display is also pretty badly uniformly yellowed, although not as badly as before. Again, it doesn't seem to suffer from any other issues. It is an SJA2 as well.
I don't have a hardware calibrator, but using the profiles Merch Visoiu posted (thanks!) I can get something that isn't absolutely horrible to look at. Perhaps with proper calibration I could get something close to my original two displays. I am too stubborn, however, to spend I sizable chunk of money on a hardware calibrator when I don't feel that I should have to (those that can calibrate at arbitrary white points are more expensive).
Unfortunately, there isn't really any way to tell how likely it is that you get a good replacement display. For every poster here, there might be another who got a good replacement the first time. Without numbers, we just can't say.
If you have time to commit to ongoing display changes, then it might be worth it to go ahead and complain about it. You can probably keep getting your display changed if you approach the right technician in the right way. Perhaps it would be useful to "probe" this issue with a local technician to see how they feel about it. It they sympathize with you (agreeing that the "to-specificaiton" displays actually look like poop), you will have a much easier time swapping panels. While I didn't have problems getting my first yellow display replaced, others most definitely have.
Otherwise, I don't think there is really anything else to do. I have sent a letter to Tim Cook, called multiple technicians, and even spoken to a "supervisor" in customer relations. They all say something like this:
"That does seem to be a problem. If you take it to a technician or mail it into us we can replace your display."
I have requested that they keep replacing displays until they get one that looks identical to a good one, but they would have none of it as the replacement displays meet "apple specifications." Because I don't have time to continuously play the lottery, I am probably going to stick with the panel I've got.
I empathize with the psychological stress, though. I cannot seem to move past the fact that I have an inferior product. I even work right next to individuals who have perfect retina displays on their MacBooks -- I can simply turn my head and see what my display should look like. It is absolutely maddening.
This whole experience is really just ridiculous. To sell a 2000+ dollar machine that is marketed on the basis of its superior display with such an obvious lack of quality control makes my blood boil. I have literally received a prohibitively expensive lemon.
I should note that a VP of the company that I work for just had the display in his retina macbook pro replaced. He noticed that the new display was yellow and has proceeded to delve into the issue as we all have. In my conversation with him, he mentioned that he probably won't bring any more macs into the company because of our collective experience (we are on the cusp of a large hardware refresh) ...Justice?
