Maybe hard to believe with everyone wanting a bigger screen here but people do read comics on 6” readers. For some comics the formatting fits the screen fine and does the job. I’ve read comics on my Kobo Clara for a while before getting a Fire HD 8 just so I could use Tachiyomi. So I think you can read comics on a 6” e-reader and I’m betting some would enjoy it. I know I wouldn’t mind it.
