Any good ebook readers for Android?

These requirements are really specific. Whites parts of black pictures in particular, I can't think of anything that implements that.
Anyway, these probably don't have everything you want, but I use Librera:
website: https://librera.mobi/
Github: https://github.com/foobnix/LibreraReader
No material you theme, but I know it has font selection, and dictionary/translation integration.
The website claims it supports custom themings, and CSS. I can find the options in my app, but I haven't touched them.
It also supports custom fonts, including user added ones.
It supports sync between librera instances (Google Drive has first class support), but not with Foliate.
It defaults to "book mode" which is page
Bit off-topic...Librera is decent but I hate that I can't use custom background without changing the opacity. It seems like it doesn't have the ability to use a background but it rather puts the image on top of the text and then lowers the opacity of the custom image, which doesn't look nice.
