As I've said before cameras can see things that are beyond the range of the human eye.
What matters is whether you, your friends, family and colleagues, or anyone else you ask to check the screen with you can can see the tint when the phone is setup in the way that makes the problem the most obvious (brightness, etc) and when the screen is displaying whatever makes the problem the most obvious.
The phones are not made for robots or cyborgs, it's what can be seen with the human eye that matters. If it can't be seen then the phone is fine.
If it can be seen and if it bothers you, DOA it and either get a new one or get a refund and wait for a bit to see what happens.
If it can be seen and if it bothers you and you just hold on to the phone you are decreasing the chances of Samsung fixing this fully in production - kind of like all the people who held on to their SGS despite having a problem with the GPS which bothered them but hoping for a fix. Whereas one million returns worldwide due to a faulty GPS would have gauranteed a fix.
