Indoors 'during the daytime' is still pretty dark in a great many rooms, often due to the preference of the rooms occupants. So it really has little to do with the time of day. Right now it's early in the afternoon for me; the sun is still up but it's overcast, my window blinds closed, and my lights aren't turned on because there is no reason for them to be on. Dark mode works great in these sort of dim conditions. It's really a matter of comfort, not fashion. As for 'at work', it's been my experience that offices generally aren't very bright. Not even remotely as bright as daylight, nor even as bright as electric lighting could be. Those overhead florescent bulbs produce a harsh shade of light.. but not all that much of it. That's why people squint or put on sunglasses when they walk out of office buildings during the day.
