How determine RDP session encryption?

Hi
RDPing to a Windows 7 machine.  I have turned enabled settings to require encryption (see screenshot), but still want to ensure that it is in fact a secure session i'm connecting to.

I did not enable "allow connections only from computers running remote desktop with network level authentication" in the "Remote" tab in system properties, as I frequently connect via mobile app RDP clients, and wasn't sure if that would interfere.

Let me know
Thanks!

Check your GPO setting for rdp server, under

Computer Policy > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host, and then click on Security.
you should see the following setting.

Client connection encryption level – Set this to High Level so your rdp sessions are secured with 128-bit encryption.

Require secure RPC communication – Set this to Enabled.

Require use of specific security layer for remote (RDP) connections – Set this to SSL (TLS 1.0).

Require user authentication for remote connections by using Network Level Authentication – Set this to Enabled.

To ensure connectivity, consider for the  latest mobile rdp apps client it will support the required rdp version e.g. see support in Microsoft Remote Desktop Apps for iOS, Mac OS X, and Android

The Remote Desktop apps support the latest Network Layer Authentication (NLA) protocol, protecting your users and your data. The apps also connect to older servers that do not support the newer, stronger encryption offered by NLA but will alert the user that they are connecting to a potentially unsafe server.

The apps use RDP 8.0 and RemoteFX for high fidelity audio and graphics. The protocol automatically adjusts for client performance and network bandwidth.
