I do. The current "retina" displays are lagging behind modern display tech. This might be fixed with the 2017 iPhones' OLED display, which might also include a higher resolution. I mean the iPhone has kept this 326 ppi display for 6 years, while all other manufacturers have upgraded their display's PPI since then, with sony in the lead with its ridiculous 806 ppi 4k Xperia 5 Premium. While that is definitely too far, I don't think it is unreasonable to ask for the ability to watch full hd movies and videos. I suggest a 1080p 4.7" iPhone display, at 469 PPI, and a 1440p 5.7" Plus display, at 515 PPI.
