I think there might be different interpretations of what "worms" is referring too
The pseudo detail, or
dots and
worms, that I have been known to bang on about
appear in the medium to high signal areas, where the filter used (decon/wavelets etc) compress any hint of feature or structure, into thin unnatural looking bright curves and wavy lines, or make all or much of the detail in galaxies, appear as uniform circular dots. Both artefacts give the
impression of resolution, when viewed at small screen size, but even a half R'sed close inspection reveals the awful fake news
....provided the image posted is actually displayed at a reasonable size in order to be able to do this of course
The granular look seen in the low signal areas or the background, is a whole separate problem.
