The difference between two images can be non-lossy, if you like.
> partially-transparent or glossy surfaces.
It's all just RGB values; there is no gloss or transparency in an image. (Image layers can have transparency for compositing, but that's obviously something else.)
If audio encoding can have "joint stereo", why not visual coding.
Many areas of a stereo image are nearly identical, like the distant background.
