I can't get my mind around this inconsistency and it's making me
uncertain what files I'm working with!

(I've posted in a couple of PSP groups too.)

I'll hazard a guess that the file in question has PNG transparency
settings that Explorer recognises and many imaging apps do not.

Be easier to comment after looking at the actual small file.
