Nah, the dimensionality doesn't mean it's preferably visible. It's only used demonstratively, when truly required. Actual Fe egos use it either constantly (E*E) or creatively (*EI).
I can often tell Fi users in videos because I get a breathless feeling from watching their monologues, it lacks the natural Fe inflection that lets me breath. They don't tend to interact with the camera in a natural way.
I wonder if non-Fe users even notice this?
