I’ve worked in film mastering so yes I am an outlier. My point was that industry guarding the DCP makes sense as the leaked pirate versions are not the same thing. In music world everyone can buy uncompressed CD, but with moving image end user can only get what is equivalent of a mp3. This includes the illegal channels. Blu-ray is say 1:40 compressed from raw data. Good enough for sure but not the theatre experience.
A 4k movie, even from a Blu-Ray, may look very nice when watched at a normal speed, but if you look at the individual frames in order to distinguish some details during a sequence with fast movements, the quality is very bad and it may be impossible to see the details that you want to see.
At the levels of compression that are typical for movies distributed by encoding with H.264, H.265 and the like, I have never seen any movie that still looks high quality when slowed down during fast action.
Where do you live? Where I live only professionals and nerds use movie playback that allows single frame stepping, it's definitely a fringe phenomenon here.
I live in the EU, but any good free movie player should allow stepping through video frames back and forth and also playing with any desired speed in frames per second.
This is not a feature that requires professional tools.
And I do not think that you have to be a pro or a nerd in order to want to see clearly many of the details of the kind "blink and you miss it".
You are right and it is an evil form of gate keeping.
Pros before bros.
Nerds are just wannabes.
The mugglers may suffer as they do not know, care or can articulate it. If they do - they are clearly nerds and we can discard them as a minority.
People conflate pro with premium. The mass market should be able to sustain premium and discount. The market might be too small for pro DCP content. But I would like the market to understand that there are 3 important segments. Pro, premium and discount.
Pro - special specific needs.
Premium - for the regular Joe who wants good quality.
Discount - for the masses.
Premium market is underserved. Unless you are willing to pay luxury prices for Kaleidescape or the likes.
It is the race to the bottom with streaming providers testing commercials. They have already succeeded with the "junk content" as the big studios wants to keep licenses for their own services.
The quality bar is set for the lowest/cheapest common denominator.
There is nothing weird about it. If a single person has the resource to decrypt and manage the logistics, then obviously DCP is the intended way a director wants his audience to experience his creativity.
As someone who's been working with cinema and video mastering, it sounds like you haven't seen the difference between professional formats like DCP and consumer formats viewed on a proper screen or projector. There's a reason we still have cinemas after all.
Even consumer equipment benefits greatly from visually lossless encoded media.
No one goes to the theater because the picture is better. It often isn’t.
Projectors aren’t maintained, or set up correctly, and audio balancing is often way off. People go to the movies to see new releases or have dedicated shared experiences
I often hear that hand waving "what the market wants". But it is more "what the market can suffer". See IPv4 vs IPv6.
I am not working with mastering as the OP. But I can see the low fidelity of streaming services. I watch my content projected to a large screen.
So I am one of those weirdos. I do not mind as I know I am a nerd. But there are more of us than you think but the penny pinchers wins as usual. "The majority do not see it". But they do. The majority went out and bought 4K TVs. They are slightly disappointed as it did not get "that much better". Most would have been just as happy with a 1080P OLED display. But only the geeks can articulate what they want.
The worst local offender is the online Blockbuster. Compression artifacts galore. But as most view content on phones the audio is stereo only. So your "sufficient" is not my "sufficient".
I get the "weird" part. No offense at all. But you are talking about optimizing for what the majority will suffer.
And it is done to save the last little penny. We could optimize for technical excellence but pride has gone out of fashion.
Even among the set of people who have something even semi-resembling a proper home theater—which is already a tiny group—I'd be 95+% would need to upgrade their gear quite a bit before they'd benefit at all much from quality higher than ~50GB-100GB blu ray rips.
(stream rips do often does look like dog shit, though—I find sub-10GB 1080p blu-ray downscales [to get the HDR from the 4k blu ray, but lower res and storage space] usually look better than raw 4K streaming rips)
