This is just a DE for Linux, it does not solve the problem that DRM is incompatible with a free platform. Get your content from another source than Netflix.

720p using widevine. I play it. It works. Even if I disable DRM in my main browser. And only isolate it to my Netflix account.

the magic trick is just to not, netflix won't even stream you 4k 90% of the time even if you do have all the requirements.
