Netflix already has their own Windows desktop app. Because it can use Microsoft's unsandboxed PlayReady DRM, it can play 1080p video while Chrome and Firefox can only play 720p.

I believe, but can't remember offhand, that Netflix will do 1080p in Edge as well.

That's correct. Netflix can do 1080p in IE and Edge (because they use unsandboxed PlayReady) and in Safari (which uses Apple's FairPlay).
