This does not work as a stealth radar, just like Wukong's passive does not work this way. Hidden units will not be exposed and you will not receive additional armor/magic resist if a hidden enemy champion is nearby, but not visible to you.

The only mechanic that still works this way is Fiddlesticks' passive, that can be seen from the enemies even if Fiddlesticks is invisible to them.
