I think the point in the design space makes more sense for game textures than sensor input. When you consider the encoding primitives, it'll only do well on images which have a mix of (a) limited palette, (b) blocks of constant color and (c) smooth gradients. Reencoding JPGs may not be too bad because of the way DCT creates little blocks of gradients and chroma subsampling reducing local color entropy, but ISTM it'll do best on images generated by humans with drawing tools. The decode speed is another big point in favour of usage in games.
