People are SO used to overly hot displays with bright blue torch-cast that when you have a properly calibrated 6500 degree display they think it looks yellow.
I am personally convinced that a lot of 'yellow tinged' display returns were actually the most accurate displays
I couldn't agree more. Making display blue-er makes everything look sharp and bright, as well as improving the visibility under sunlight somewhat (to my eyes anyway) that companies often "cheat" with their displays and consumers all got used to it.
On a somewhat related note when I received my first Galaxy S, I couldn't believe the atrocious color temperature which was nearly 10,000(!, yes, it's "over 9000"). After seeing so many praises of that OLED display, I was flummoxed and enlightened at the same time. If they didn't use the same skewed color temperate, things wouldn't have looked as sharp and bright and that's what consumers thought was good, just like boosting bass and treble in audio.
I'm curious to see what measurements the new iPad displays come in. I remember some of the iPad 2 displays, despite called for "too yellow" was actually on the high side of the 6,500.
