At office I only use light background as glare is really annoying on my iMac if I set a black background.
At home on my Macbook I sometimes set dark mode at night, I don't work completely in the dark even if I turn on the light I don't have glare.
I'm using dark mode on Twitter and it works, as long as there are no bright pictures in my feed. That's the problem with dark mode, it works while everything is mostly dark but if you open an app not supporting dark mode it gets really annoying.
