You can find lots of buggy images with bugs in all possible ways. But the vast majority of the images have consistent shading, perspective, and even global illumination. Some of it can be done in "screen space" (as in some standard game 2D post-processing filters) but lots of them couldn't work this way. At some low level, pixel patterns are rendered and I guess you could say that this is "reproducing observed patterns". Would you say that about a 3D game engine as well that does the same when it textures local regions of pixels? A network is layered for this particular reason. The lowest layer will have less "understanding" than the higher layers.
