Unity still has its macish elements, true, but I think the post-Unity GTK+ and general in-default-app experiences tended to move toward "doing their own thing", rather than aping Windows or macOS. Also, while the Unity side dock is iconified like macOS', I think it's functionality more different than the old Gnome2 bottom panel was from the macOS dock. All subjective I guess.
