I love my iPhone 6 Plus, but this seems to have developed over the last month or so, or I just noticed it. Seems to be a backlight uniformity issue along the right side of my device. See attached image. I noticed it when I was on an all white webpage...it's weird because I never noticed it before. It may have developed since I recieved it. I have a Genius Bar appointment tonight, I will let you know how it pans out.
