In general they’d get better bandwidth savings for the same quality and decode effort by shipping the higher-resolution image with more aggressive image compression (using http://bellard.org/bpg/ http://bellard.org/bpg/ or something, not JPEG, and ideally running the decode in hardware). Seems like a dubious method overall. The main impression I get is “woo! neural nets can do everything! let’s use them everywhere!” I don’t believe their claim that this is “comparable or better than the state of the art” for image upscaling without much better evidence than they provide in their paper.
