While you can try to install an older version of the Netflix app from APK mirror. https://www.apkmirror.com/apk/netflix-inc/netflix-android-tv/netflix-android-tv-2-0-build-295-release/ If that doesn't work your best bet might be to launch the Netflix site using something like the Pelican browse. Now I have an older 2013 Sony TV with a long dead smart platform. What I did was connect an Nvidia Shield and use CEC to controll the shield using the Sony remote.
