Chances are that I'm not interpreting your setup correctly, but based on the picture with choke and nanoVNS, you were only testing the DM mode - impact of your choke on power sent from one side to the other side of your choke.
You need to test the CM (common mode) suppression, and that get's done differently - for example, you short both sides
Would be great if you can clarify your test setup and then mention what attached screens shots are for :)
