Widevine kind of works on Linux IIRC, but hardware accelerated VP9 decode is a huge issue still. It was fine for a while, then Google broke support in Chromium and made it work only in their ecosystem (ChromeOS).
Haven't looked at it in a while, but last I did it "worked". Resolution on netflix ends up being fine - 1080p - but I couldn't help shake the feeling that its worse.
...check bitrates and sure enough...less than half. Never worked out why, but that's a bit of a show stopper when combined with no online shooters.
