This is my first iPad so I can't refer to that but here is a picture next to my mid-2009 Macbook Pro. I turned the brightness up to max for this picture for easiest comparison.
The reason the MBP is a little darker is that the screen was slightly more tilted back. As far as color, its the same. So, unless my MBP has a yellow tint, mine should be fine. And even if it does, I don't care because it looks just like my all my other stuff.
Thanks for posting. Your iPad looks like mine, mildly yellow tint.
