Same boat
I feel your pain OP. Glad you are happy with your screen finally. I am on my 3rd 2015 rMBP 13". My first 2 had noticeable pink screen tint, my current (3rd) one is much less obvious than the prior ones, but there is a bit of uneven uniformity on the left side of the screen as the photo shows. There was only one perfectly white 13" Pro at my store out of all the 13" on display (edit- at the table I was at). I also note that the 2nd unit I tried had a very loud / clickety keyboard and shallower travel compared to the first one and my current one. I still have a genius bar appointment for tomorrow morning but may cancel it. I think I'm way too OCD about finding the perfect screen, I'm sure they will tell me they don't see any issue with mine. Sadly will probably just settle for mediocrity and move on.
