Thanks, unfortunately I was among the ones who just cannot live without touch ID, so don't have another OLED display next to me. I read a few pages of the thread (but definitely not all over 300 pages), but still could not get a clue if mine is good or not. The display looks uniformed though (also in a dark room), just when I put it together with my other devices, there is a noticeable yellow tint.
I did some research and it seems like a lottery to get a good quality iPhone these days, and I am just super afraid after a few draws, I end up with a even worse one...
