Just to be a pedantic twit I looked up whether Capture One supports Pixel Shift, their answer (from 2016 but not updated)
Phase One
And to add to the pedantic-ism, I just checked the Capture One forum and found that Sony Pixel Shift is also NOT supported. I did find my request to have pixel shift added (and ignored) to the v12 - wish list. I don't think Phase One really cares about supporting Pentax all that much, but it sure beats LR to death.
Here is the list of supported cameras:
Capture One Pro 11 Supported Cameras
Please note the far right hand side, and the K-3II and K-1 are the only two cameras listed with having Pixel Shift (I know that is not true, but I have a whole bucket of pedantic here)
