Indeed the photos above will be deceiving because the screen becomes more yellow/green when you look at it from an angle.
I have noticed though that the colour temperature is more yellow than my iPad 1. However, I never pick up the new iPad and think, its wrong. It was only when I compared the two I realised. However, my phone is more yellow than the iPad.
I don't really understand why the backlights seem to vary so much between units. This is not related to Apple. This is discussed with SO many phones and tablets...the consistency simply isn't there. I saw 3 HTC EVO 3D phones, and was one clearly pinky, while another was very greenish.
I would say my iPad 3 is towards yellow, but not enough to ruin it for me.
