Adding an AMOLED theme.

Is your feature request related to a problem? Please describe.
The feature request is not related to a problem but a quality of life improvement. I mostly listen to audiobooks at bedtime and an AMOLED theme would be really helpful.

Describe the solution you'd like
A theme selection option in the settings that shows options like Light/Dark/Black.

Apparently the application follows the system level theme setting:

This is not enough to enable pure black (AMOLED) themed.

I like the idea. A black/dark switch option for the dark mode would be nice.

An AMOLED/black theme would be amazing, really hope this will get implemented

Also wish for a full black theme !
