similar image search not always working as expected

Hello,
Sometimes similar image search does not show all possible results, even
though I use similarity 55 - 100%. It does find it though with
similarity set to 40%, but then of course it also finds a lot of false
positives.
Besides of file format and size the two images are identical, actually
the image used for the search is just a smaller .jpg-version made from
the .png original with a small added watermark.
Over this night I let digikam rebuild all "fingerprints", but even after
a restart of dk if doesn't find those images when set to 50 or 55%.
Is there a problem with .png files? (although it happens only with few
images, other .png's of other images are found)
Can I better the results with any trick?
I can provide access to sample images in private, but those are nudes...
Kind regards
Daniel

version without having to go through the albums with countless photos,
even more when I forgot the name of a model :-) )
