If one is happy with it, fine. Just do not compare it to a previous iPhone. Just looking when I got the ip 7 it looked good, when I compared it to an ip 6s it was obvious it was less bright and more yellowish. I have not seen any matching the ip 6s screen at retailers or carrier stores yet, all of the ip 7 were more yellow and less bright. The more I used my ip 7, the more obvious it became.
I know, do the procedure in the setting to change the hue and just make the brightness higher. Changing the hue makes the display look blue, increase brightness will just make the battery take a hit and I use my phone extensively during the day.
Why would anyone post a pic of the back on an iPhone if the emphasis is on the display? Color me confused.
