QF5/6 - 3 or 4 Class ? What happens to Premium Economy

[fom]

Hello

as per Seatguru the QF5 (SYD/FRA via SIN) and QF6 (FRA/SYD via SIN) are 747-400 with three classes only (Y, J and First).
Is this true or is SeatGuru outdated ?
If indeed 3-Classes only, what happens to Y+ bookings ? J-Class seats with Y+ treatment ?

Thanks
Fom

Seat Guru is outdated.

There is one two class Y/J plane. That mostly does QF581/582.

The 3 class birds are Y/Y+/J, with the four class birds obviously being Y/Y+/J/F.
