You say "it always fails", but also it fails because "extra 3d information is not worth the logistic cost".

Couldn't you conceive of a future where the "logistic cost" drops so incredibly low, that the cost is less than the benefit of the extra information?

For instance, if the soft-AI systems like KoboldAI and StableDiffusion were re-trained to handle the conversion of 2d media into 3d media and guided in the process by an appropriately talented director with a tech team and artists to support it, an entire mediacentric cottage industry could erupt just with managing the licenses to convert old movies into explorable 3d interactive adventures.

How cool would it be to have a chat with Humphrey Bogart in Casablanca, or to make a mad dive to save Mufasa at the last second and see how The Lion King would play out without his death as a motivating factor? If you could do all of that and more in a VR Cineplex it would probably be more entertaining than Disneyland and available at every Mall in America.

Honestly, that's probably a trillion+ dollar idea, but implementing it would need an insane amount of money, time, skill, processing, and resources plus dozens of large egotistical companies working together.

As I said above, true holographic digital screens could make 3D seamless and ubiquitous. At current computing trends, that appears at least a number of decades away from consumer gear.
