That's from 2013, though. It's 2016 now and OLED displays are widely regarded as being more efficient (except for when displaying pure white), brighter, more vibrant, less reflective, and just as accurate as LCD displays are. There's a reason the S7/S7 Edge have been tested and reviewed by DisplayMate as having the best smartphone displays. Putting my iPhone 6s Plus's display next to the the S7's OLED display and the difference is staggering. Everything looks so much better on the S7's display.
I compared pictures, web pages, etc. and had it set to the most color accurate mode and saw no difference in terms of color between the images display on both screens, but on the S7's display everything really popped out at you and was overall more vibrant and better looking. It's hard to explain without seeing it in person, but after seeing them side by side it's clear that Apple has fallen behind in terms of display quality (that's not to say Apple's displays are bad; they're not... they just aren't as good as current OLED displays). I really hope they move up the adoption to OLED to the iPhone 7 instead of next year's iPhone.
