Note the presence of working face detection in the K-3 EXIF for image 2 WITHOUT LIVE VIEW BEING ACTIVE:
Quote: Face Detect : On (5 faces max); 1 faces detected
Face Detect Frame Size : 0 0
Also note that the
Nikon D800, with it's 91k metering sensor (only slightly more detailed than the K-3's 86k unit), also does stuff like:
"exposure control considering face brightness is achieved by the enhanced face detection performance of Advanced Scene Recognition System", "Auto-area AF detects human faces and prioritizes their sharpness" and
here "The RGB sensor with approximately 91K (91,000) pixels built into the D800/D800E offers more accurate face detection. When used with viewfinder framing in exposure modes other than M, the camera balances exposure between a portrait subject and the background, even when the subject is backlit.."
So it seems not impossible for the K-3 to do a similar sort of job as the D800, given the similarity of the metering hardware. Pentax (perhaps) just hasn't disclosed this capability yet for K-3 PDAF. Maybe it's still v0.5 beta code, or something they are reserving as a listed feature for a future camera.

That's what I've been saying.
Something along the lines of this:
