I think you may be underestimating how aware they are regarding level of location easter eggs they provide. This is just my guess, but I'd be surprised if the location tidbits shared isn't something carefully considered by the production staff and I'd be shocked if there weren't very real and detailed discussions/negotiations about how much to show.
When I’m bored, I enjoy picking up these Easter eggs.
