I think you are right for movies and TV shows, but not for "comics, manga and graphic novels" and I'll add books as well. Since those are much cheaper and easier to produce than TV shows and movies, they can be created independently, without the need to optimize for earning tons of money. Indie literature and comics are very diverse in the storytelling.

But I acknowledged (and dread a bit) that the audiovisual storytelling is such a strong force that any discussion about storytelling, even when specifically talking about literature/comics storytelling, is dominated by audiovisual references. Any creative writing workshop/course that include sci fi and fantasy genres will inevitably mention Star Wars as example for whichever technique. The more literary ones will mention some Oscar winning movie, etc.
