^ I see.
K-3 Mark III Owner's Manual
From Page 62 in the manual:
You can make settings so that the recognized subject is prioritized while autofocusing when [AF Active Area] is set to [Auto Area] or [Zone Select].
Page 63 has a table for the Active Area AF & tells you what each type of autofocus does.
So my guess is that basic subject recognition alone is handled by those autofocus settings in any mode outside of
AUTO. We already know that subject recognition is available in
AUTO.

^ Here's is where the confusion seems to come in. According to what I gathered from the vague Section 6, there's an additional
"Deep Learning Technology" that seems to work on top of the subject recognition once you turn the dial to
AUTO or set the
Custom Image mode to
Auto Select in any mode outside of
AUTO. The funny thing is that the owner's manual doesn't mention anything about
"Deep Learning Technology". The downside is that you're very limited when shooting in
AUTO or you're stuck with whatever image tone the camera decides to give you when using Auto Select. You might get Natural, Bright, Landscape, Portrait, or whatever the camera thinks is appropriate for that scene. That kind of sucks for jpeg shooters that rely on the OOC jpegs, but RAW shooters can keep using their own RAW converter settings & get whatever color they want.
Good old vague Pentax. Hahaha!
