I am not aware of any of the major gaming consoles uses Wasm or Wasmi in particular for their engine but I am sure they'd let us know if they ever used Wasm as execution model for all their games.
What's more likely is that Wasm is used in some indie games for those major game consoles.
I know of one game engine (Firefly-zero) and one game where Wasmi is used as game engine and plugin engine respectively. There likely are more, but that's what I know for a certain.
I experimented with running Doom using Wasmi and it even works in the browser, thus in a double sandbox where Wasmi itself is compiled to Wasm: (references in the article)
