Reply to comment by Givemeahippo in How big is a high format movie file theatres get for their screenings, and can we also access these versions as consumers in any way? by niklasd2003

The DCP would be very lightly compressed though. Even the best Blu-rays are compressed down to a 100GB disc. It might make a difference in very dark scenes where compression artifacts are most likely to be evident. But probably not worth it.

The other thing is that the DCP will likely contain 10+ audio channels. Now, whether there is any home theater system that can decode and play it (maybe a properly set up Dolby ATMOS system?) is TBD.

I know in the r/fanedits community there's a lot of stock placed in getting work print copies and 35mm open mattes of movies.

Up to a certain degree of compression, a video file is effectivelly loseless, though...

What exactly are work print copies and 35mm open mattes of movies?

Essentially, the full image frame as captured by the film or the digital camera sensor, usually in a tall 4:3 aspect ratio before being cropped down to a cinematic wide screen format (1.85:1, 2.35:1 etc.). So it shows off much more vertical space. To be fair, the director and cinematographer would compose the shots for the target aspect ratio, so the extra vertical space is usually visually uninteresting (sky, ground) because all the production design and composition will be set up for the frame they wanted to shoot. But purists are always after it for preservation reasons.

Also, of note to this discussion, it is typically very lightly compressed as it is the version intended to be used for post production and editing so is in the highest available quality.
