Youtube detects your capabilities and sets it automatically. Unless you're using an obsolete potato network or watching low resolution stuff you'll likely get x265.
Netflix is similar. It defaults to h265 for Netflix content (because they want it to look good). Partner/licensed content uses the inferior codecs that use more bandwidth to achieve worse quality.
youtube has never and will never come to support x265 they even tried to block support from chrome becuase they hate it that much
they support x264,vp8/vp9, av1 and soon av2
they literally started and entire organisation to take on mpeg called aomedia
Pretty much everything modern except Apple. Intel since 11th gen (2021), AMD since Zen4 (2022), Samsung phones since 2021, Google phones since 2021, Mediatek since 2020.
With modern lifecycles the way they are, that's probably ~60-80% of everything out there.
