Terminology, what is PAPR an abbreviation of, is pseries (hardware
interface) equivalent with PAPR?

Also all discussed above is supported by Raptor Talos/Blackbird
hardware right - the Raptor machine exports PowerNV to the host system
that runs on bare metal, and the host system (= Linux QEMU-KVM for
now) will export a virtualized pseries/papr Power9 machine to the VM
guest, which runs at close to full bare metal speed?
