There are two different things going on here. One is detecting Chrome OS and the other is determining the set of stream profiles. If you were to change your useragent to get Chrome OS, like the GitHub says, this would alter code paths in other areas related to DRM. However the fix that was found was simply pushing the stream profile into the array. This doesn't affect DRM at all.

The fix from the Netflix side would be to find a suitable alternative to user agent sniffing for h/w accel and swap that in to this code path.
