iPhone 7 Plus display dingier than iPhone 6 Plus display

I just upgraded from an iPhone 6 Plus to an iPhone 7 Plus. The first thing I noticed was that the display on the iPhone 7 Plus seems to be "dingier" than that of the iPhone 6 Plus. It's not as bright for the same setting. At maximum setting the iPhone 6 Plus is noticeably brighter, and whiter.

I thought the iPhone 7 Plus was supposed to be brighter than the iPhone 6 Plus. Is there something wrong with my new iPhone do you think?

All the settings are, I believe, the same. I restored from a backup of my iPhone 6 Plus I saved in iTunes this morning.
