It's certainly not perfect, but I discovered just the other day that the "Big Picture" web browser (embedded chromium, IIRC) does work with Netflix. I think maybe you can't get 4k or 5.1 sound unless you're using Edge or the windows store app though.
The resolution and bitrate is burned in for each quality level they stream. I'm topping out at 3000kbps/720p in Chrome. I don't have a Windows machine to test on, though.
When I last saw it reported, 1080p is the max unless you use a Kaby Lake CPU and Edge (and the premium higher-price 4-stream Netflix subscription). The Windows Store app does not go above 1080p.
