I was not talking about the ability to scan 35mm film in 4K or higher.
All that modern films are edited digitally (scanned original 35mm or shot with digital cameras and all post production happens on computers) where the VFX and CGI is created in no higher resolution than 2K or 2.5K.
Particularly the computer rendered CGI can not be done in 4K because of the extra cost in render time. For example if it takes 48 hours to render each CGI frame.
To my knowledge, the only film that has had a 4K workflow to date, including VFX (about 1200 VFX shots) is The Girl With The Dragon Tattoo (that might have changed but just not reported).
Movies like The Hobbit, Prometheus and Gatsby, Total Recall and the latest Spiderman was all shot in 5K, but they only have a 2K finished version of the movies.
They can of course use the 35mm print version of the film (probably do), but again, that is still a digital 2K version of the movie printed back to 35mm film, and by that doesn't have the full quality like a film shot and edited in 4K.
35mm film doesn't have full 4K resolution, so old 35mm films scanned at 4K or higher will never have full 4K resolution like a film that is shot digitally with a camera that has 5K or higher resolution.
So it will be a debate of what is "real 4K" and what is Real 4K. Depends also on the "Look" of the film if the resolution quality really becomes apparent.
