So after going through 3-4 7 Pluses ALL with yellow screens (not just yellowish, but yellow with uneven tints, dull lifeless colors where orange looked brown), I waited two months and just got a phone with a pretty good screen. It looked perfect at the hello screen (blueish like my old 6 plus), but after setting it up got warmer. It is MUCH MUCH MUCH better than the earlier phones I got. I don't notice the warmer tone at all, and I finally understand why some people raved about the 7 plus screen. The earlier models I got must have been defective, because orange, actually looks orange on this new phone.
Here is the really weird thing:
Like I said, orange looked brown on all 3-4 of those phone I went through earlier in sept/oct. Everything was dull and lifeless. Colors looked washed out.
Now, when I activate the app switcher, and the cards of multiple apps comes up, my orange goes back to that dull brown color. When I bring the app back to the front, it turns bright orange again.
What does that mean??? That is not the panel itself then, it must be a software/firmware thing.
Unfortunately, they overpolished the antenna down to the silver aluminum. So I am undecided about keeping this one. But the screen, the haptic engine, EVERYTHING feels better about this phone.
