Terrific. Thanks for posting this graph again.
If you think that all iphone 7 screens are perfect, and any yellowing is intentional, and that when I put my yellow phone next to a display 7 and the display 7 had a much cooler screen temp, then the display model must be defective , plus my 6S which looked like the display 7 must also have been defective - than good on ya.
I cant spoon feed this to you any more. you either go look at the pics with your own eyes, compare your phone to display models yourself, or whatever else you want to do to get informed, or you move on believing this nonsense that its just correct temps and people are overreacting. Two temperature screened versions of the phones exist. Its been proven again and again, with pics all over. Go look at it. Or dont. But dont try to convince the world and yourself that theres only one screen out there.
Let me post this example - AGAIN - of a good temp iphone 7 screen:

Pictures mean NOTHING in determining relative white points. Show us a single instance of a calibrated test showing a recent iPhone at less than 6500k measured. What you want is the occasional overly blue screen. Fine. But stop insisting the rest of the screens are defective. You have zero data to back that point of view up while ample data has been provided demonstrating otherwise.
