Just like many have mentioned here when I bought my iPad 4 the screen seemed a bit on the warmer side. Not bad but noticeable. Now after a few weeks of constant use the screen seems to have cooled down a bit and the whites are whiter. I heard these screens need to settle in a bit, I suspect thats what happened. So those of you with warmer screens, give it a bit and let the screen break in a little. It looks great now!
