I applaud your patent leather collection. I have been searching SF as well as the internet and it is rather common to wear calf with black tie. I am not certain if wearing calf takes away from the formality or the zest of the occasion; perhaps more experienced posters can chime in.
Theoretically one should wear patent leather. I wear a pair of highly shined calfskin plain toe oxfords. The sheen of patent leather works in the evening if you like it. Perhaps it is contextually more formal with black tie, but keep in mind one could wear punch cap black oxfords with a morning coat. Anyway, I see no issue with calf though prefer a plain toe.
