Matching theme on LG G3 Circle Case AND LG Urbane Smartwatch

I have a LG G3 VS985 with circle case AND an LG Urbane C948 smartwatch. I want to update both clock/watch apps to the newer "roulette-style" of the G4. I've seen the app run on both in instructional videos. How does one upgrade to newer app AND set both to have matching watchfaces (or themes) so they look and function the same?

thanks for specific details!
