I'm not clear on this myself. It's actually been a while since I've seen this, so I'm going to watch the movie again this week and post some more extensive thoughts. Do you mean the historical context of the films themselves or the subject matter of the films? In either case I don't think you have to worry. No prior knowledge needed for Parajanov imo. His films are like poems, just put one on and let it wash over you. Still waiting on those Pre-Code era Bette Davis recommendations.
