Well, I'm not a power Calibre user, so I'm not quite sure exactly how to do a comparison, but I'll see if I can. I wouldn't necessarily know what to look for, honestly. Social DRM can be done in varied ways, some obvious, some not so much.

EDIT: Just took a quick look at the size of the downloaded Adobe DRM file prior to deDRM, i.e. as it sits in my Digital Editions folder ... and there's a fair file-size difference!

Adobe DRM epub = 2,028 KB
Kobo SDRM epub = 3,435 KB

OK, have the SDRM book open in Calibre Viewer, I'm not seeing any pages with my name on it though I don't have time to scroll through the whole thing.

At the bottom of the copyright page, there is this:
