I wonder if it is related to coming from a northern country (Scandinavia) where ~1/4 of the year is really dark.
In at least one case, it wasn't just me. I used to work editing photos on California's central coast and after we moved to a building with loads and loads of skylights, and got a bunch of new glossy-screen iMacs, it was really hard to get color accuracy if you wore anything but a black or white shirt. It was like staring at a mirror all day long. Eventually we got umbrellas to blot out the sun and that helped.
I have just been using stylus and using dark themes for sites I use often, but would love a more automated approach, especially for sites I don't use that often.
I would guess that all Scandinavia countries have similar rules, and there's actually a minimum amount of light you're legally allowed to have in a room. The law in Denmark for instance actually require a room to be insanely bright.
