This is a fantastic question.
It is possible that “Curious George: A Very Monkey Christmas” falls into this description. It is perhaps more likely that there is an OS, and the two major characters (George, the Man in the Yellow Hat) have threads that would both be the same domain, and there is no RS.
Does anyone here have very young kids and want to watch it and find out? It’s almost the season!
Edit: I think one reason this might not happen very often, is that broken stories can be seen from multiple perspectives… they aren’t locked down, so to speak. Which means they no longer always feel like they have four clearly delineated domains.
