The SXFI amp will create virtual surround from any 5.1 or 7.1 PCM source and appear to Windows as a 7.1 speaker configuration. So Netflix on the Windows app (NOT on a browser) will work but, like MLE said, it's hard to really tell the difference as most movies/shows don't use rear channels to a great degree. I tried it out with Altered Carbon and preferred Atmos to SXFI. Personally for media watching I use Atmos as it does not adulterate the overall audio the way SXFI does. For games though SXFI is very accurate and that wins out for me.
