With the quest? Yeah so am i. You very much still have compression. Even at 800mbps bitrate, thats still not the same as a proper display port headset like the Index.
In fact you very likely don't see the smear probably because of the blocky JPEG of the image as is, and maybe you're used to it because you watch a lot of streaming videos rather than high bitrate vids. Not meant as an insult, that's just the way things are nowadays.
