For many people, home viewing will be better than what they see at their local multiplex. If you’ve got a 4K TV with Dolby Vision and a movie that also has Dolby Vision, the metadata in the movie file will interact with the player to deliver a precisely correct playback of the movie. On the other hand, a lot of theaters are using ten year old 2K projectors that weren’t top of the line to begin with. Those projectors were financed in part by movie studios who collectively agreed to chip in on digital projectors to help in the transition from film to digital. That money isn’t there anymore; studios aren’t helping to pay for upgrades. Theaters are already operating on minuscule margins. There may be money to upgrade one auditorium to Dolby Cinema or IMAX but there is rarely the budget for new 4K state of the art machines for each room. So on one hand, the rate of innovation moves faster at home. On the other hand, the people making the movies know what most theaters are stuck with, so they’re not necessarily going crazy to produce higher resolution masters that most of the audience will never see in that quality.
