If the compression can take into account the sub-manifold of potential outputs that people would actually be interested in watching a movie about it can achieve enormously higher compression than if it doesn't know about this.

Unproven - but yes like I say - a new type of compression

Not new. If you have a preshared dictionary even zstd can give you better compression.
