I've compared the visual appearance of "direct by WiFi from Amazon KFX" on a PW3, with the "Download to PC, Transfer via USB for <device target>" which at last use was still and AZW and it looks identical. So obviously the KFX has two aims at least, stronger DRM and dramatically reduce traffic cost for Amazon if someone has the 3G model of a Kindle. They'd not care about broadband + Wifi, or people using WiFi points with a mobile dongle, only their own account traffic. Obviously the KFX has not obvious archive text files, however it must have the same structure of content, styles, images and index.
Perhaps you missed the bytecode compiler reference? Expecting a KFX to have the same structure as an epub/azw3 is like expecting a Pascal p-code file to have the same structure as the Pascal source code file.
