I don't think you're wrong on it being overlooked, when I hear people talking about Mario games it's usually Galaxy 1/2 or 64. Even Sunshine seems to get talked about more, while Odyssey just gets kinda forgotten about, even if everyone loved it back when it came out.
Edit: conversely, I don't think BotW had that effect at all. It's still talked about regularly, people still wanna play it and still reference it when talking about other games. "This is like BotW", "that's something BotW was better/worse at", stuff like that. Never hear that sort of thing about Odyssey. But maybe that's just the people I talk to.
