I think "narrative storytelling" I think is too broad, that can absolutely work in VR, but it means creating a different experience from the ground up.
A "TV Show or movie" I agree is going to have a hard time of that, but just like theatre is different, and games have limited interaction, storytelling can take many forms ("narrative storytelling" doesn't have to completely avoid interaction or influence to tell a story/plot IMO).
I think good AR/VR could open up a different type, the way "Holodeck" writers in Star Trek were shown as a separate skill I think could hold true. Creating believable/rich characters with AI + related environments, and support adapting (even if it is just minimal) story lines will be challenging but I'm sure some people will create interesting experiences, they just need the tools to do so.
