I think it's always problematic to compare to images upscaled via nearest-neighbor. The big pixels are hard to parse for our brain, we detect all the blocky edges. A good content unaware upscaling would be nice (one of the default photoshop algos) I also wonder what they used for the downscaling. I see 4x4 pixel blocks, but also some with 3px or 7px lengths. This looks pixely and is supposed to be a source file?: https://raw.githubusercontent.com/Tetrachrome/subpixel/d2e28... |

The pic with the boat on page 13 is interesting. In the SRGAN version I would take the shore for some sort of cliff, while the original shows separated boulders.
