I'm fine with the resolution. I'd be fine with 1080p (I see a very slight difference on the 6 Plus vs. the 6, but only when viewed side by side and examining closely...in real use, it's irrelevant). The improvement is so minimal, in that it just doesn't make a difference in usage (while the difference between the older non-retina devices to the current screens actually made things easier to read and changed how the device was used). There's nothing more I can do with my device with a 1080p screen than with the 6/6S as it stands now. Quad HD is just dumb and 4K is laughable on a screen this small. It's just wasted memory and processing cycles.
Much more important at this stage is color accuracy, color gamut and contrast (as in accurate contrast, not blasted hyper contrast for punchiness sake.)
