I did read it :) What I am saying is: If they are blocking everything but chrome os intentionally, it would have been easier. According to widevine docs [1] chrome on desktops does not support security level 1. They could have and probably did block access to 1080p content on level 3. Which leads me to believe that netflix relaxed security to allow 1080p on level 3. As you said the next step would be to replace the user agent detection client side.
