DVD codec probably allows for a certain amount of error correction to recover from scratches, images can still look readable to humans despite a bit of noise, I wonder if there’s enough overlap there to meet in the middle and have an image that also stores data

A bit like those AI images that were also working QR codes from a while back.[1]

Would be a really interesting challenge to find the point where maximally useful data meets a maximally good image. The data goes through layers of encoding to become data on disc, so it wouldn't be easy, but we already have a one-way translation here in this tool.

Even if that is possible for a pristine disc, you really do want that error recovery for discs people are actually expected to use.
