...The next thing I wanted to know was whether the yellow cast observed in some photos of the new MBPs meant that the new screens have a different color temperature than the old ones. They don't. Visual inspection shows no color cast, and looking at the color profile for the screen with the ColorSync Utility shows that the native white point is identical to that of the previous-generation of MBP 15" screens. That would be standard 6500K or D65—the color of daylight on an overcast day. However, looking at the screen from an angle makes the image brown-yellowish. I was a bit worried about the viewing angles, but it's not as bad as I had feared. If you sit back a bit and adjust the screen so it's perpendicular to your line of sight, you're in good shape. When leaning in, however, you'll look at the corners of the screen at enough of an angle to introduce color shifts...
