I do not do anything really professional with my MBP, so I do not need exact color perfection, however paid alot of money for this thing, so would like it as accurate as possible. Anyway, I do not have a 1/3 yellowing on the bottom, however the entire screen is "Warmer" than other monitors. Not a big deal however, I think it actually looks pretty good. While when I awake my MBP from sleep, for about 1 second, the Color profile is different, and looks significantly richer in color and looks really nice, and then it goes right back to whatever my default is (Color LCD) which is the same colors, just looks more washed out. I dont know if that makes any sence, but the Apple Default Background is alot more Blue, and Deeper, Richer, and Vibrant.... Just for about 1 second. Any help on getting a better color profile for my MBP?
