Tried it last night with my Brent Mason. Humbucker mode no problem single coil problem.
today I just got done getting the HFS/Vintage pcikup set with PRS drop in 3 way w/push pull tone installed in my boys SE singlecut. 22 fret guitar. Tried the harmonic at 5th fret. well in coil tap pretty non existant. full HB mode it`s there but no where near what it is in the bridge position.

Tried this on my NF3 this morning, yep definite volume difference on 5th fret harmonic on neck pickup vs any other (including neck/middle combo).
Also tried it on my NF equipped SE and same deal, I must have got the neck pickup location "right".
Also tried it on my CU22 Soapbar, no volume difference there.
I first noticed this issue with my 513, 5th fret harmonic fine in single coil mode but almost impossible or very low output in the humbucker modes, I emailed PRS support about it they said to send the guitar to them, not a cheap option form the UK, a few months later I met PRSh while buying an ME1 and mentioned the issue to him he simply said no you won't get the harmonic at the 5th fret nothing wrong with the guitar, so I just remember to select another pickup if I want 5th fret harmonics.
