My rMBP is in the shop to get the Samsung display in for my LG which had minor IR. I keep hearing how yellow the samsung displays are when they come back. Do people get them that are happy with them, and would notice if the coloring is off? As in, are there some good installs? Now I'm wondering if I should cancel my order because even with the IR the LG had a beautiful screen, I don't want an off-color one.
