scorespro.com has a live score of GER-BUL and usually this means there is a stream somewhere (or an official live score), but I can't find one
There was definitely no stream for that match. I don't know about official live score, but I strongly doubt it.
By the way, a few minutes ago Bulgaria won against Germany and guaranteed the bronze medal in the friendly tournament. Germany finished in 4th place.
Sportv is broadcasting starting right now the final match between Brazil and Nederlands. If Brazil wins 2 sets, then will win the gold medal.
