azw is not azw3.
An azw is mobi with Amazon DRM. There are various kinds of mobi. The basic mobi is like HTML3 and has no CSS. Extensions were added to do periodicals. A non-Amazon mobi/azw might have a .prc ending; The mobi format existed before Amazon bought Mobipocket.

An azw3 is really Amazon's version of epub2, and only has some limited non-periodical extensions (It's basically subset of HTML5 and CSS, like epub2).

An azw3 (KF8) and azw (KF7) are thus completely different things.
There are other Amazon Kindle Formats (KF) and several variations of KFX too.
