I'd say that's pretty irrefutable proof... Really the only thing you didn't show was the installed game in ux0, but i find it hard to believe that someone would buy the game digitally and physically just to throw us for a loop.
There is only on physical US version as well (no "greatest hits version" not that vita has those).
So the only real question then is why does yours work and no one elses does? has anyone tried installing a verified non working sly collection using a more recent Vitashell?
Maybe he modified the module. I has that problem with Neptunia game.
