I recommend setting it to disabled by default, and manually enable it for websites which need it using the "Invert listed only" button.

My 24" 4K display i use during the day with 0% brightness. Obviously at night this is too bright so i have to reduce the contrast which really hurts colour depth. Dark mode helps a lot then.
It's funny, at first I just thought it was me. But I took my old VT520 one time and I was really surprised how darkly it can paint a perfect screen. Even in a dark room I can set it so low I can barely read it.
They don't care; it's that simple.
For dark mode I just use dark reader.
Plus all sorts of other things over the years.
