‚ÄčIf the secure path is provided by the OS, then in some cases it can
include hardware decoding which becomes especially important for 4K. Sorry,
I probably shouldn't have included HDR here - it's just that most HDR
content is available in 4K at the moment, but of course you can have lower
resolution and still get the benefit of HDR.
