A precondition is likely that one has mainly watched CGI-heavy movies for most of one's life. Compared to old school analog movies or fairly raw photography that looks as fake as the Coca-Cola Santa. There's a rather obvious lack of detail that real photography would have catched.

Indeed, a great (if counterintuitive) example of this is The Wolf of Wall Street. I bet a lot of people would be surprised at just how much CGI is used in that just for set/location.
