I think that's a different category, though. Those backgrounds are actual video recordings of real places, not 3D environments modeled from scratch. It looks 'real' because the background actually exists.

It's still 100% CGI compositing and definitely not all of them are real places or real objects.
In that specific 15 year old example they're mostly composited, you're right about that.
