Since your adapters obtain DNS automatically like mine do, all that will show is the gateway as it's the one giving you the DNS. If you set a manual DNS (on your computer), it will show exactly what DNS your using.
OpenDNS manually set on a computer will show this with the ipconfig /all command. Even if you set a manually DNS on your router, it will still say the same. Easiest and best way to get your real DNS servers is this site:
IP/DNS Detect
This site is actually very useful to make sure your VPN/WebRTC isn't leaking your IP but it's also great for seeing your DNS as VPN (well most of them anyway) will change your DNS to one of their choice to increase security/anonymity.
