My first, second, and third instinct here is to say this is pretty obvious and sloppy fraud. But it did remind me of the famous case discovered by David Kriesel where Xerox scanners changed documents in surprising ways. The caption on the YouTube video linked here is entertainingly accurate.

"On the scale of things too horrible to contemplate, "document-altering scanner" is right up there with "flesh-eating bacteria". Since 2006, Xerox scancopiers literally are making stuff up. They, for example, replace digits with others in scans. The replacement digits are layouted perfectly into the page, so the errors are hard to see. Sounds unbelievably insidious, but it's true. Drug prescriptions, construction plans, just anything can be affected. "

And now practically every phone camera "enhances" the image via AI that might invent details. Most famously Samsung adding details to photos of the moon.
