I shoot 4K and imo the benefit is mostly for youtube since it gives a higher bitrate. With that said, yesterday I re watched The Room for the 100th time, this time on Blue-Ray. That film has everything working against it, the lighting is bad, the set is bad, the locations is bad. But still I couldn't help notice how the s35mm film still simply killed.. scratch that.. Kidnapped, tortured and murdered the look of any 4K video out there. Im such a sucker for the look of film its unbelievable. Don't know why I posted it here, but it was the thoughts that came to mind after reading this thread.
