Apple has released a public beta of iOS 9.3. Its major new features:
iOS 9.3 is a major update to the iOS 9 operating system, introducing a long list of new features and improvements. iOS 9.3’s biggest new feature is Night Shift mode, which is designed to automatically cut down on the amount of blue light an iOS user is exposed to at night by shifting to more yellow tones for the iPhone or iPad’s display. With iOS 9.3, there’s a number of changes for educational users, and the iPhone is now able to pair with multiple Apple Watches.
Of course, “Night Shift”, as Apple calls it, is a wholesale copy of f.lux.
In any event, Apple also released a public beta of OS X 10.11.4.
Of course Night Shift is also a copy of LiveDisplay in Marshmallow. Unlike other red-tint apps I’ve seen, LiveDisplay changes the display’s colour balance using hardware drivers (rather than simply applying a fullscreen translucent red layer), which is nice.
As far as I can tell, f.lux under OSX constantly tweaks a custom color profile, which could arguably also be a hardware based change. I don’t know if the iOS version worked the same way.
It doesn’t mean that color profiles were meant to be used that way, and performance sometimes suffers as a result.

Yes, you’re right, but on Android/iOS I think a third-party app would need root privileges.
Twilight doesn’t need root privileges.
I suppose it would be too much to hope for a setting to get rid of that unsightly dock background. Its like virtual poo smeared across otherwise beautiful device.
