There's currently a known issue with apps not being able to see that Play + services is installed in the profile in some cases. This is being worked on and + should be resolved soon.
+Since there's no OS integration beyond fallback code to make it function without any special privileges, there isn't a way to launch the settings activity. We'll need to make a tiny app providing a way to launch it.
