To further the discussion, can you provide some screenshots of your eBook, with embedded fonts, from the K4iOS reader? From the sideloaded AZK?

Unless something has changed very, very recently--which it certainly could have, without us noticing--the K4iOS reader has been a KF7 reader since nearly the beginning. It even has some KF7-KF8 crossover glitches, like displaying things that have KF7 fallbacks, as well as the KF7 coding (for example, text boxes). I freely admit I don't test every book on iOS, for myriad reasons (mostly, the ridiculously time-consuming AZK, sideload, yadda, nonsense. I checked a book with fonts today (again, post-upload at the KDP), and nary a font was to be seen.

And are you still seeing these fonts, after you load the book at the KDP, and then download the post-conversion MOBI, from Step 7? (Download Preview File). I presume you keep a test account, for these purposes, so you can test books post-upload at Step 6? (There's a lot that happens at Step 6, which can alter the outcome and appearance of the book. We test our books at the KDP, and the file that you download at Step 7 is indicative of what you'll get, rather than what you see from Desktop Previewer).

If you haven't, I would recommend loading the mobi at KDP, and downloading the Step-7 mobi, and then viewing that on the iPad, to see what you're getting. Just a suggestion.
