complete black dark mode to save battery with amoled screen

[jpduyx]

Describe the bug By my knowlegde Amoled screens don't light the LEDs when a pixel is completely black. To save battery it would be great when there is a complete black background darkmode.

Now the background in darkmode stays grey lighting the amoled LEDs

Expected behavior I would like to save battery and gave a complete black dark background without any LEDs of the background lighting up and saving battery.
