The PPL is just the licence; an appropriate rating is also required. Ex-military jets flown under CAP632 require an Aircraft Type Rating Exemption which will only be issued following a bespoke training package agreed by the CAA. That is where relevant ability and experience is determined. The display aspects are totally separate and are in accordance with CAP403. The type of licence, as has been said before, is no indicator of pure flying skills and airmanship which are the relevant aspects with respect to flying aircraft such as the Hunter.
