Unfortunately no. Just exchanged mine today as it had a yellow tint all down the right side. The replacement has a slightly yellower tint, but its even across the screen so I'm happier with it.
No, it's not even. Mine has a dark spot on the far left that's noticable when scrolling white pages.
The left side of the screen is also slightly yellow, but it's only an issue when reading books or magazines.
At least my iPad 4 didn't have dust, dead pixels or hair underneath the screen like the iPad 3's I went through.
