I would have rather thought it would be some sort of image enhancement algo gone wrong.

  Yeah it's definitely some overflowing brightness enhancement thing. You can see that in the before/after photo that someone posted.

    I was thinking something similar: it has a distinct posterization look that I tend to get when I mess around with images and reduce the bit-width of my input a little too much and my integers overflow. But those tend to result in "zebra stripes" like patterns, so you're probably right that the issue is more one of not using saturating integers while amplifying a value above the bit-width of its container.

  You can boost contrast to make low bitrate images look better, so it could be a combination of both.
