It seems that way. But what is it about the theming of the whole park itself would necessitate that?
A 'movie studio' theme would bring about the expectation of being part of the movies. Does a 'celestial theme' also necessitate that?
This is just Universal doing what Disney is doing... making everything IP. Or, to put it as often phrased "crammed into every nook and cranny and shoved down our throats!"
Even Six Flags feels the need to theme a totally unthemed coaster with a flat cut-out of some IP at the entrance and to paint the metal a color evocative of that slapdash IP.
Only our dear Saint Dolly has escaped the IP mandate.
