They are. Possibly a small bit of CGI if they need to show something they just CAN'T do in the game (but they didn't in S11 so really I don't even expect that), but nothing major like S9 & S10. If they were putting together another production team to animate all that I'd think we'd have heard SOMETHING about it. But we haven't so yeah.

The CGI isn't really needed anymore regardless.
