You mean except for 12 or 24 months from now when the OLED iPhone is announced.
Last I recall they looked a bit off. Nice, but a bit off. That said, my experience with OLED screens is a bit dated, so maybe the color reproduction has improved.
I was recently in the market for a phone, and considering an iPhone SE. But unfortunately I've got hooked on Lumia OLEDs, so I'm taking one last cheap hit from the rapidly cooling MS pipe while Apple gets that duck lined up ;-)
Also, I now have an excuse to not install the stupid apps friends and family and random guy at the bus stop recommend.
