Regarding DRM I don't see how it'll survive "Camera in front of the screen" + "AI video upscaling" once the second part is good enough. Can't DRM between the screen and your eyes. Until they put DRM in Neuralink.

No, but media can be watermarked in imperceptible ways, and then if all players are required to check and act on such watermarks, the gap becomes narrow enough to probably be effective.
