Hi there,
I wanted to share that I successfully imported DAZ Genesis 9 with full facial profile into CC4 as non-standard character (Humanoid). 
I had to use 3Dx7 and the legacy DAZ Genesis Extension method, because I was unable to complete the workflow using CC4 Facial Profile.
Here is the work-in-progress with original DAZ shaders:
