Question What are the benefits of Calibre converting epub to kepub?
I'm both new to the e-reader world and Calibre. I installed Calibre 5.9.0 and a buncha plugins for use with my recently purchased Kobo Libra H2O:
Kobo utilities
Kobo touch extended
KePub metadata reader/writer

I tried comparing a few epubs transferred to the Libra twice: once by coping the files directly, renaming them to kepub.epub; and by converting them to kepub by Calibre.
I also tried to diff the two files, which shows some significant changes to formatting. ( I set Calibre's Common Options -> Page setup's output profile to Tablet so that it'll not mess with images).

The results, so far, seem indistinguishable to my untrained eye, which is good. But the question arises: What are the benefits of all these changes Calibre does to the text. Isn't kepub a super-set of epub? can't I simply transfer the file over? Can I tweak Calibre to simply copy epubs over and just rename them to kepub.epub?
