The promises of the film experience at the dawn of the digital era were never realized. All of the work has been put into minimizing the costs of movie making and distribution. Consumer display and audio technologies are the exception, but movie theaters still haven't incorporated automated ambient effects like local haptics or spatial audio, smellovision, lighting, etc, like in stage productions. There are no custom data tracks or queuing allowed in industry formats. Anything would have to be built separately and manually synced. Despite our art and technology, there is little excess or imagination in film today, and it is desperately resistant to change.
