Yes, CAT IIIB. There's a way to tell, by the way.
If you're sitting in the first 6-7 rows of an A320-series aircraft, the autopilot disconnect sound is called the cavalry charge, feel free to run a web search and bring that sound up. Normally, you can hear the cavalry charge when established on the glide slope. On a CAT IIIB, after they make you turn off your phone, you hear the charge during the roll out.
