I posted that picture at an "extreme" angle. What I meant was that the screen gets gradually purple.. In normal use circumstances, what happens is that my screen is never all white (actually yellow), no sweet spot, half of the screen is always slightly tinted.
I use my iPad to read, and at night the white page looks sepia. It bothers me, and at the smallest tilt the farther part of the screen gets red tint.. so I end up with half yellow, half reddish screen.. it bothers me so much
Looks like your new iPad has yellow tint, which might get more whiter in about a week or so. It's never going to be as white as the iPad 2, because the new iPad just has a more warmer tint.
Also, the new iPad gets a lot dimmer than the iPad 2 at its lowest brightness setting. I think that is a good change, because I always found the iPad 2 too bright in a dark room.
