Dr. Raymond M. Soneira, DisplayMate:

At first glance the iPhone 7 looks almost indistinguishable from the 2014 iPhone 6 and 2015 iPhone 6s. Actually, the displays are the same size and have the same pixel resolution. But that is as far as it goes… The iPhone 7 display is a Truly Impressive major enhancement and advancement on the iPhone 6 display… and even every other mobile LCD display that we have ever tested… note that I hand out compliments on displays very carefully. And for those of you thinking of Emailing that we got hand-picked units, the iPhones were purchased retail from Verizon Wireless.

The iPhone 7 got extraordinarily high scores, and this from someone who really knows display tech. Read the post for the details, but this is one area in which the iPhone 7 is hands down the best in class.
