So the problem is that there is no way to tell whether the camera
simply didn't take the photos correctly - or whether the transfer
out to Linux screwed them up - or (perhaps) they are using some
very obscure dialect of JPEG that GIMP, etc can't display.

I've never seen any of those things happen before - so they all
seem equally unlikely.

One thing you might try:  Find a JPEG file someplace on the Web
or whatever of the same size as the ones that are getting screwed
up.   Copy it INTO the camera (ie mount the drive as before and
copy the file FROM Linux TO the camera's memory.  Now, unmount,
disconnect the camera, etc.

If you now follow the exact same procedure you used before to
copy large JPEG files off the camera to retrieve the one you
just put there yourself - then if the image comes back intact
then you'll KNOW for an absolute certainty that it's not the
transfer process that's messing up.

If the file comes back screwed up in the same way the others
do - then you know it can't be GIMP - but it could still be
some problem inside the camera with storing large files.

Once we've narrowed down the problem some, we can move forward.
