According to Serebii, No.
However, even if it did, all UB catch rates are 1/10. That means that dive ball's catch rate would be 7/20. that is still lower than a pokeball. But, I've caught Nihilego at full hp with a dusk ball first try, and I've caught Regice in a beast ball, so this doesn't seem very unlikely to be possible.
Edit: I remember reading that dusk balls don't work in Ultra Caves in the daytime, so I don't think they'ed increase the dive ball's effect in the Ultra Sea.
