So no OLED until Apple goes to the dark side with iOS. I'm still wondering what the star attraction of the 6s could possibly be. A dual-lens camera would be, but it doesn't look like the 6s will get that.
No OLED until Samsung opens up current gen OLED to other manufacturers. They currently only sell their previous generation panels to other OEMs. Apple sinks a lot of marketing into their displays. Being a year behind a Samsung device in screen in terms of quality wouldn't be their best decision.
