I think that is correct as they don't count as an "device" - in Netsight Console you also have only the switches and the controller listed correct ?
As the AP has no SNMP agent running you can't discover them as a SNMP device.
If you use NAC in your network you'd use OneView to see were everything is connected to.
In the example below I search for the AP name and I'd see the switch port, the home controller, NAC that was used to authenticate the AP.
