Yeah, I'm sure it's better be blinded by the plain white color everywhere. I can't even use some wallpapers on iOS 10. I'm actually more focused on the content when I'm using my old iPhone 4 on iOS 6. That thing is a joy to use. The fluid smooth animations and easily distinguishable elements that creates contrast between things is so nice to use and look at. iOS used to have a personality, but now it's soulless. If they aren't gonna change iOS design they need to add at least a dark mode in iOS 11.Probably not because the actual reason for flat and non-skeuomorphic designs is to get the UI out of the content you want to see/use/etc. Together with current IT-trends like AI we won't see that coming back ever again. I'm 99 % sure.
Back on topic: I find it very interesting that we haven't heard better seen anything how iOS 11 will be and look like. Definitely feels different than last years.
