is it possible to dump and play bought psn games?

I'm trying to run a dumped psn game. Unfortunately the psn game won't start because its encrypted (Infobox: ineligible).

I used my sisters console (obviously latest fw) to download it from my psn account. Afterwards I copied it to an external hdd, only to copy it to my ps4 5.05 internal hdd. I get a message that the game wont start (hen activated) with a "buy it from the psn store" button.

I thought, maybe I should dump the game to an usb drive, so I can create a pkg with orbis on pc. But...

is it possible to dump and play bought psn games?
