Man, I've been reading digital comics years before I was reading digital books. I've only ever used CBZ or CBR. Never bothered with a table of contents either. For the most part, they are single issue comics, so a TOC would seem silly. Even in collected editions, I tend to read them much faster than a novel.
I also read comics on a tablet and use programs meant for digital comics (Perfect Viewer on Android, Cover on Windows). I don't add comics to calibre. There used to be a calibre like program for comics, ComicRack. But for me it was shaky at the best of times and is no longer developed. So I gave up metadata.
