I think there’s a bit of needing to play to the audience there too.
Voyager has a deliberate contrast built in with the Captain Proton episodes, where they show a 1930s era world inside the holodeck. Even down to turning characters black and white 🙂
It’s probably a need to make a bridge to allow the audience to easily relate to what’s going on up on the screen. If it’s too different, people just go “what the hell” and switch off …
