>I actually think the quantity of bizarre imagery whose content is unknown to humans is pretty darn low.
Historically, this just hasn't ever been the case. There are images today that wouldn't have merely been outlandish 150 years ago, but absolutely mysterious. A picture of a spiral galaxy perhaps, or electron-microscopy of some microfauna. Humans would have been able to do little more than describe the relative shapes. And thus there are more images that no one will be familiar with for centuries. But if we were to somehow see them early, even without the context of how the image was produced I suspect strongly that clever people might manage to figure out what those images represent. No model could do this.
The quantity of bizarre imagery is finite... each pixel in a raster has a finite number of color values, and there are finite numbers of pixels in a raster image after all. But the number is staggeringly large, even the subset of images that represent real things, even the subset of that which represents things which humans have no concept of. My imagination is too modest to even touch the surface of that, but my cognition is sufficient to surmise that it exists.
