Fair point, but no. Not that I wasn't sure before, but I found the video again (I see no way to get a YouTube link, which is a pity), and it's definitely "the one" at Place de l'Étoile. And for whatever it's worth, the game's marker isn't at the Carrousel either (I didn't check it in that much detail before), but at the start of Champs-Elysées near Concorde.
