Perhaps DrSlony want mean about to record histogram in metadata. PNG support
this feature as a dedicated chunk, but not Exif, IPTC, and XMP.

This can be done in a dedicated XMP tag from digiKam namespace for example...
But this tag will be only managed by digiKam of course. Editing image in gimp
for example will not update histogram XMp tag.
