What level of papal distinction does Prior General Gilles Wach hold?

**Prior General Gilles Wach** is referred to as a **Monsignor**, meaning he must hold one of the three levels of papal honors. I'm not sure when he became a monsignor, but apparently it was before he founded the ICKSP (no confirmation though). His coat of arms has both the galero and tassels all in blue (consistent with his chapter's color scheme), so you can't tell from there what his papal honor is. He also wears a black cassock with a pellegrina and blue piping and fascia, while other canons from the ICKSP usually wear plain black cassocks on similar occasions. I've also seen him in one picture in a blue ferraiolo over the cassock I described above, which if I'm not mistaken is a privilege only granted to supernumerary protonotaries apostolic, but that's not conclusive evidence, so please help if someone knows!
