Yep.
Some really old models only get MOBI. The rest AZW (even ones that support KFX). Afaik, Amazon only sends KFX versions directly to the device and not via USB transfer.
Kindles with firmware up to 5.10.1.3 and Kindle for PC 1.19-1.24 get KFX that are Alf-friendly. Those on higher versions have as-yet non-removable KFX DRM.
The MOBI and AZW downloads using the "Download and Transfer via USB" method are unaffected and are all "disinfectable".
