Ten years ago we got fun and exciting errors in scanned documents.[0] I'm looking forward to ten years from now, when I can read about a conviction being overturned because an AI-enabled camera did a similar "enhancement".
Something like this actually played a significant role in the trial of Kyle Rittenhouse. The prosecution tried to enter some low resolution images into the record and his defense argued it shouldn't be admissable because it had been upscaled. They asserted that by upscaling it, pixels had been added to the image which may not reflect what the camera actually captured. IIRC, the image wasn't very detailed and it was pretty difficult to tell where his rifle was pointed.
I don't know whether either side's argument was right, I'm only saying it happened.

I think it's undeniable that pixels were added; that video looks like it's lower resolution than an iPad's display. There have to be pixels added to make it even full-screen, much less zoom in.
I think the underlying question was whether pinch to zoom does nearest-neighbor upscaling (i.e. each pixel becomes a 2x2 block of the same color), or whether it does something more clever to "guess" at what those pixels would have looked like (something like averaging the pixels nearest to it).
The former seems fine to me. It preserves the original image, and zooming in really only gives you a blockier representation of the original. The latter is inventing things the camera didn't capture, and the method of interpolation could substantially alter the resulting image. Wikipedia has a pretty good example of both next to each other: https://en.wikipedia.org/wiki/Image_scaling
To be fair once I get my Bright Side of the Moon Lunar advertising corp set up distributing images on the moon, we'll be in a great position to sue Samsung for failing to reproduce my advertising with full fidelity.
