Yes,I'm not convinced that the S7 edge does not have a better display than the iPhone 7 plus according to display mate.
The iPhone 7 is low res and doesn't even come into it.
I've not owned the note 7. I had the S7 edge for one month and used it alongside my 6S plus. The S7 edge probably had a better display but there wasn't much in it. My 7 plus has a better display than the 6S plus.
You believe that. But displaymates review of the 7 plus screen was after the review of the s7.
You touted displaymates review yourself with the note 7 display, that was after the review of the iphone 7. You concluded from these facts that the note 7 has the superior display.
I think your reasoning in this was solid and sound. BUT you should be consistent . The same displaymate however reviewed the 7 screen as the best screen , AFTER the review of the s7.
That , for me, doesn' t mean that the iphone 7 has a superior screen.
But, your way of determination and debating of which phone has the best display, should be consistent.
