This has to do with the long-standing animosity between Apple and Amazon and the lack of desire to make devices and software compatible. Kindle for iOS accepts both sideloaded and e-mailed .mobi files, but it displays them incorrectly. The AZK format is supposed to closely emulate the final ebook file that Amazon sends to a paying customer's iOS device.

Incidentally, KP2.901 does not generate the AZK file for regular reflowable ebooks (only for fixed layout) and still emulates the iOS devices incorrectly, showing the old KF6 part of a .mobi file.

but have you tried renaming the *.AZK file with one of the extensions that KindeUnpack does recognize -- just to see if it can then be unpacked?
Nope, none of the available extensions work. Looks like this AZK format is a new bird. But KindleUnpack 0.62 works fine with .mobi files generated by the latest version of KindleGen, 2.9, and Kindle Previewer 2.901 successfully reads the split Mobi7 and Mobi8-only .mobi files. (As mentioned above, the Kindle for iOS emulation of KP2.901 cannot read the Mobi8-only split files, but this is a problem with Kindle Previewer, not KindleUnpack.)
