For me, I find that a very dark gray background with a light gray text color is best. I like dark themes, but I get "ghosting" if the contrast is too great.
This is hard for virtually everyone to read. I don't think making the reading experience terrible for 99.999% to make it work for 0.001% makes much sense.
I think what I described is what a lot of dark themes use. For example the NY Times Android app. Their light text color is not pure white, and the background is not pure black.
Could you go into more detail as to why? It actually is my preferred style of presentation. Hopefully you do not prefer yellow on blue, as it often gives me migraines, especially if there's lots of text.
