Oh come on, of course they do. That’s why Uni has been spending so much money and effort on building fabulously detailed themed lands like Diagon. Most guests might not register every detail in the same obsessive way fans do, but they realize a difference between, say, the entrance area to IoA and that of the Studios, and it impacts their impression of the park.
As to the “Studios” moniker, everyone on these boards understands that the park’s overall theme has completely shifted from opening day. The “behind the scenes” conceit of the Backstage Tour and Alfred Hitchcock and Earthquake and the like is almost completely gone, leaving behind only a few vestigial elements, most notably the now out-of-place sound stages.
If they wanted to integrate the sound stages, they could have made the area Minions Studio, but they again took a lazier option because they wanted to use pre-existing design elements.
The cafe looks great. It’s an improvement over the Monsters Cafe despite my preference for the Monsters. But the big lightly themed tan boxes remain an issue in the modern Studios.
