Watching this video: https://www.youtube.com/watch?v=ar-zShkKExk at the 2:08 mark he says the iPhone 6 screen is brighter than the iPhone 6 Plus. He says the 6 has 606 nits vs 574 on the Plus.This is the first I have heard of this. Anyone notice the difference? Or is it negligible? I haven't heard this mentioned in any of the other iPhone reviews and I have watched a ton of them. Just curious if anyone who has used both phones noticed a difference in the screen brightness at all? Thanks.
