Winter, I'm mostly reflecting upon my first bub here (because #2 engaged so early, so wasn't big before I noticed a difference), but I think I noticed a slight difference. Bub can engage bit by bit, and they can rise up and down, although at 36 weeks, I'd say bub will just nestle down further and further bit by bit.

I think I noticed a difference because bub was posterior, so bum sticking out, which made a drop more noticable to me. I'd say how obvious it is will depend on how bub drops and how bub is positioned.

But yay! Any dropping is progress!
