I went to two AT&T stores and one Verizon store today to compare my iPhone to the displays. In all cases the store display models were way brighter.
Right: my IPhone 7 Plus 64GB black AT&T
Left: Verizon model iPhone 7 plus black
As you can see, both are set to max brightness and both have auto brightness turned off.
There is a real issue with mine.
I have tried restoring all settings, restoring the phone (DFU), toggled the display zoom, and performed hard resets all without seeing any corrections.
