Solution: Within CC, set the Black Level setting to High. This value will correspond to the LG C4's Full setting for the Video Range.

Extra: I was too timid to use values that didn't correspond with my TV. Ended up messing around with all values and CC's Black Level > High value will correctly set my LG C4's Video Range setting to Full.
