Dunno, I have never seen AoA display on the PFD and there is nothing about it in my FCOM, so there is good chance my company has not taken that option but AOA DISAGREE has been in our QRHs for quite a few years, with list of tail numbers it is applicable to, so there are some planes that don't have alpha comparator. All I'm saying that even AOA DISAGREE alert is a customer option not necessarily packed together with alpha display.
