Comment (by Balling):

 >The video still looks washed out when I do that. Only tone mapping fixes
 its appearance.

 No, it does not. Are you sure you understasnd how to play HDR?

 >Also I'm unclear on what you're saying I'm wrong about.

 >doesn't have proper HDR metadata
 >The video is thus washed out and oversaturated on SDR displays

 This implication is wrong. HDR metadata is what amakes a video HDR10, not
 HDR. PQ functio0n makes video HDR.
