Looks like most of the cards in the top 20 support H.265 4:2:0 (NVidia 10XX and up), just not 4:4:4 (NVidia 16XX and up). I don't think the steam hardware survey is a good sample of the wider computer market though - the majority of people using youtube/netflix/etc on x86 devices are probably using Intel laptop chips with integrated graphics, not $500+ dedicated GPUs. (Although presumably this is probably becoming less true over time, those low end users are moving more and more to mobile devices and smart TVs/chromecast/console, leaving workstation/gaming systems to be a larger percentage of the market)
