Impossible to say. Even after three years of flying DL more than 125k miles a year, the check-in is still spotty at best. Sometimes it works, sometimes it does not. If it doesn't work, you can use either one at CDG, the kiosk or the desk. There will be another document check at the gate in which they frequently re-check your documents in particular visa (such as green cards, etc.). Be also prepared of some public pat-down and carry-on search.
