This looks amazing, this is how dark mode should be done instead of just replacing white with black.New Notifications and Control Center view are very bright, unlikely previous which were more translucent. They should automatically darken through the day, and it would achieve as much as Night Shift does for your eyes in the evening.
I can wait until 2017 for dark mode for apps but I don't think it should wait for Notifications and Control Center, but arrive before the GM of iOS 10, and be part of Night Shift.
