Any reason to pick this over Immich?

Well this is fan fiction so I guess the answer is no?

Isn’t Vizio like the cheapest brand? Or one of them, at least. Some of the most budget oriented brands might take that approach but I don’t see others like Samsung, Sony or LG doing that (at least based on their prices).

It’s pretty likely that the TV price is not subsidized. They might just want to squeeze as much money out of you as possible.
