In my opinion, American cinema is in a transition between the Digital Era to an Ultra HD Era.
In the last decade, technology in film has been developing at an exponential rate. From the introduction to the first digital cameras that shot in HD to curved televisions, more and more stuff just keeps getting put out to "enhance" the movie making experience.
Like the Hollywood Renaissance, studios nowadays have to compete with each other to make sure the public buys tickets to see their movies. With audiences no longer having nearly as much time as they used to, marketing teams have to make their films look worthwhile.
It started with James Cameron's Avatar. Everyone saw that film. It was in 3-D and was made basically just with computers.
Nowadays, if a film doesn't have enough pixels, is it even worth seeing? Of course many indie shooters are still shooting 1920x1080 but a regular theater would never show a film like that next to their 6k blockbusters unless it was a national sensation.
Indie filmmakers are now getting access to the big guns the studios are using. 4k is no longer an impossible goal for the low budget shooter. DSLRs are now looked down upon instead of looked up toward. Looks are now just as important as story.
