Is it possible to come up with any check if the passed icon is the same as the app already has?

I tried to md5 but the checksum is different for .icns file and the result of get command for same icon

Yes, it seems like transformations can happen behind the scenes that result in a different binary file when you extract the image.

I'm afraid I don't know how to compensate for that - short of round-tripping an assigned image, which may not be practical (by that I mean: assign, extract, and keep the extracted form as a reference copy; if a given file or folder has this reference copy assigned, extracting it will apparently retrieve an exact copy of it).

ok, I got the idea. will try to "cook" smth in that direction.
