Yes. The size is slightly different here to show it off better, but compare left and right in https://peterc.org/misc/queen.png (both are the same "quality" and file size but the right hand one has incorrect quantization ordering)
Also it turns out it wasn't a Kodak camera, but a Casio QV 10 I had much earlier. You can sorta see what I meant here: https://medium.com/people-gadgets/the-gadget-we-miss-the-cas... .. though the resolution is far lower too. The weird blocky color aberrations aren't just JPEG artefacts but related to the same quantization ordering issue I think.
