@CuriousOne If you make that an answer, I think it'll be the best so far.

comment Spin of black hole?
I only remember it as a theoretical result. The only physical scenario I can think of is if gas is funnelled to a supermassive black hole following a galactic collision and settles down into a disc, it could be aligned differently to the black hole spin. But as you say, this only tells you about the mutual orientation of the black hole and disc.

comment Spin of black hole?
If memory serves, the accretion dynamics depend on whether the accretion disc is co- or counter-rotating relative to the black hole's spin. So if the accretion disc extends to, say, the innermost stable circular orbit, I think you can work out which way the black hole's angular momentum is aligned.
