Dithering not functioning correctly since version 1.6.7

[ImagineBlaze]

As the title, unsightly artifacts will be produced on backgrounds when set to Low brightness, such as during gameplay with high background dim.
This is probably due to the "Use Hardware Dither" function in the game's options not working as intended.
It might be also related to the implementation of the "Set Background Quality" option, regarding color spaces.
osu!droid might have been using 6 or 7-bit color spaces since 1.6.7 which if true, will cause these artifacts.
Fixing the "High" quality background setting to display 8-bit colors might solve this issue?
The differences can be seen below. (All examples are in 25% brightness)

Additional suggestion: Have an option to support 10-bit color spaces since there are phones which support it. (Have an option in Set Background Quality being "Very High*")
