Yeah, I would worry about what that top version of me would do. But I suppose, with the simulator it would likely be possible to see. Just run another instance of the universe to the point I found out I'm in the simulation chain, but don't let the new instance see the black sphere. This serves another purpose... when the level that thinks it is the top level sees the level below them running this test, they will have to again wonder if they are in one of those simulations. So they will again have incentive to be nice/benevolent to the simulation chain.
