I am sorry to becoming that guy... Ceramic in the neck and Alnico in the bridge. Doesn't make much sense, but it is what it isYes, Transition humbuckers. The standard injectors singles are listed by Dimarzio as Alnico 2, and the EBMM spec sheet I have says "injectors w Alnico 2" so I don't know what that's about, but yes, Injector singles (or very similar) and Transition humbuckers.
There was a period in the LIII production (in 2020, 937 and 938 build codes) when Luke switched to custom Music Man humbuckers (ceramic in the bridge, Alnico 5 in the neck) and the HSS model has Cutlass single coils.
