Well, I just found out the answer to my problem: for the Kobo app to detect a cover image, it has to be named exactly "cover.jpg"...

edit. What I now find very strange is Calibred-related: until now, I was naming the cover file "couverture.jpg" (which means 'cover' in french) in my ePubs, and the thumbnails in Calibre were appearing correctly, with no white margin or anything. And when I name it cover.jpg and add it to Calibre, the thumbnail has white margins on left and right. Why does this happen? I don't understand this behavior at all...

second edit: OK, problem solved. Renaming the cover file in the book browser in Sigil removed the semantics so Calibre generated the thumbnail from the first xhtml file (cover display), I guess.
