I've had it just over a week. I'm actually debating returning my it! The design is impeccable. The retina screen is smooth and crisp. It's just that to me the white balance of the display is too warm. My photography teacher friend, who has an eye for this kind of thing, noticed it seems off too. At first I thought it was a bit yellowish. She thinks and I now agree it's more of a red push. I even noticed the Apple logo glows a little pink. I've tried Apple's built-in calibration tool. I can't make a profile that looks neutral to me. I don't have a radio spectrometer to calibrate it. And I'm not going to go out and buy one. It's a such a let down considering my iPad retina has what I consider neutral whites. Otherwise I really love the computer! Argh, what should I do?!
By the way, this one's got an LG screen. I can't see any image retention. I haven't done any tests but I have not been looking for it either.
Here's a pic I took that illustrates my conundrum. The retina is on the left. My old MacBook Pro is on the right.
Am I being too picky? It seems that all Apple laptops come with this color temperature now...
