If your software does something dumb when my theme switches to black on white during the day then I am just going to avoid using it...
Personally I alternate between light on dark and dark on light (the latter sometimes together with OS-wide colour inversion feature).
Dark background is hell for anyone with astigmatism. It’s fine with 80x24 (vga text mode), but for anything higher feels like light needles on the retina. With astigmatism everything that is bright and small is duplicated, which means small characters is very difficult to read.
