The people who “do agile right” are out there. Just, like the agile manifesto says, they’re authoring their own processes. And because of that, they don’t have to call it agile - or really call it anything. They just go into work, figure out what needs doing, and take responsibility and do it.

I’ve worked in plenty of teams that did this sort of thing. All different. And at different scales - startups to big tech to game jams.
