I'd be happy to contribute to the research effort if we could find a target book that wasn't Rowling...

My first effort at compare was a bust, because I'd forgotten that I'd already assigned tags and such to the Adobe DRM book. So, I imported the Adobe DRM book into Calibre
again, then exported to a folder without doing
anything, other than letting Calibre remove DRM.
Selected the SDRM book, went to compare, and there seem to be various differences. I'm a little confused, because I'm not sure what I'm doing or even which book is which in the compare panel now, (LOL!), but, there are, from quick observation, uuid differences, image size differences, and differences in the spans for the page-map IDs, in terms of the order the info contained within appears.
So it seems multiple sorts of changes going on. I'll let someone else go for the definitive statement on what might be different and whether it's removeable. Since I've no intentions to share such books with anyone other than my husband, I'm
for social DRM if Adobe DRM should bite the dust.
Right panel:
Code:
<span id="page-5" role="doc-pagebreak" epub:type="pagebreak" aria-label=" Page 5. "/>
Left panel:
Code:
<span aria-label=" Page 5. " epub:type="pagebreak" id="page-5" role="doc-pagebreak"/>
There ya go...
