I was disappointed to find that my Nexus 6P has a [screen uniformity problem](https://dl.dropboxusercontent.com/u/28717002/N6_vs_6P_screen/IMG_3280.JPG) and I'm curious how prevalent this is? I've already RMA'd, and hoping I get one that's not like this in the exchange. But perhaps this is commonplace and I'm just too picky/OCD for this technology? I noticed during phone setup something was off, and took the above picture with the [Display Tester](https://play.google.com/store/apps/details?id=com.gombosdev.displaytester&hl=en) app @ 50% brightness on the defective pixel test on the all white screen side by side with my Nexus 6 and it's obvious the 6P screen is half pink. Is this common to have partially pink screens?
