Found the remaining issue!

It seems that if the file extension isn't in uppercase XMB will ignore the file, so this would mean that psn_package_npdrm fixes this automatically when packing the PKG. Once i fixed the extensions thru ftp all the artwork was displayed, in all screen resolutions.
Final request/question for
@aldostools and
@lmn7, i read through the whole thread but i couldn't find the final version of the crypt.c file (only the initial code lmn7 posted). I would like to look into possibly porting this to Python 3 or even using PyPy, maybe that can speed things up even more, but then i need pkgcrypt.pyd to be recompiled again with the proper python.h version used for the port. If it's too much asked no problemo, both of you (and the original creator) have delivered awesome work with this tool.
