Anecdata: Reportedly my great grandma, born in the 19th century viscerally reacted to things that were fictional movies of the 1960s like they actually happened. She could not distinguish between recorded news and recorded drama.
I think it's a matter of our 'priming', what we're used to: If you're used to digital recordings that seem real to actually be real, you'll be tripped up.
If you have no such expectation, you're less inclined to buy into the reality of something that is shown to you. That you have to believe some version of events that you pick up is a false dichotomy.
You can also not believe any version until you get more substantial proof.
