Also it kicks in and gets really strong hours before I go to sleep.
Hopefully Apple themselves will do it better.
F.lux on desktop has always worked that way though, I think. It should essentially be rendering the blue component substantially darker (up to removing it, depending on the temperature setting), instead of alpha blending with orange.

Luckily, since there was a lot of positive feedback to the implementation of this feature in the 7.0 preview, it has been backed at the driver level for 7.1.
Now the feature works perfectly and has no performance impact.
It also opens the door to a wide array of other modifications :
-color adjustements
-temperature shift
- color-blindness compensation
Basically you can apply any matrix you want on the screen output.
