Seeing Bartholomeus from afar, he looks like an ordinary orthodox monk, though he wears his hood particularly deep, so that his face is mostly hidden in the shadows.

Seeing Bartholomeus from close up is not very different. Although, one might suspect there is something odd with his face - a reason for keeping it in the shadows of the hood.

In court however, and in general when in a Kindred context, he'll remove the hood. There is no reason - from his perspective - to be embarrassed by the effects of Caine's curse on his Nosferatu body.
