Describe the bug
There is a black theme option, but most of the time there are some random tones and other (useless) coloring what just defeats the purpose of using pure black theme, the one you would expect to benefit from AMOLED displays.

Expected behavior
I think it is expected that the app respects "true black" and "true black for tweet cards" settings. The latter is not even a thing, as shown below, where you can see that the card is not really black.
