You'll get your public IP, it won't signal whether you are behind CGNAT or not.

Check your WAN, if it's in a private range then you're behind CGNAT, likely going to be 10.0.0.0/8 for most ISP's but all the other private ranges count too. Otherwise it will show a public address that matches your "whats my IP" website.

CGNAT should be using 100.64.0.0/10 per RFC 6598.
