Does the discovery kit ship with a valid licence for aptX and the other optional codec’s such as aptX-LL?

When I use the “Version” command to return the BT Address, then it also lists the CODECs, and among them is APTX-LL.  
Does that mean there is already a valid licence in place on the module, or do I still need to load the demo licence using that software?

e.g.

BlueCreation Copyright 2016  
Melody Audio V6.0.40  
Build: 1464972430  
Bluetooth address 20FABB075DA2  
Profiles: A2DP HFP BLE SPP PBAP MAP  
Codecs: SBC APTX APTX-LL  
OK

Kind Regards, Joe
