Depth channel?

I've seen pretty good depth estimation algorithms that work off of 2D images, even without the use of AI.

Those depth estimation algorithms can't be used to distinguish a photo of a photo from just a photo. They will report false depth in a photograph of a flat photograph.

Yes, that's my point. You can't rely on the depth map in the image metadata to be the differentiator because it can easily be faked with depth estimation.
