There are multiple reasons for a user to want "dark mode":

* I just want everything to be dark on my screen because I like it.

* I am trying to use this device in a dark place.

* I want a dark, low-contrast background that doesn't compete with image colors.

The solutions to these three problems are all some kind of "dark mode" but each one needs a different solution. Sometimes one "dark mode" might work in conjunction with the user manually changing their brightness settings depending on the lighting in the environment, but not many people seem to design for that.
