In the world where the PS4K exists:
Games are released for OG PS4, but they're highly downgraded versions of PC games, or if they're exclusives they're downgraded from the original assets / vision in order to optimise the game and get it to run on weak hardware with a poor CPU, and also you also have a '4k version' for the PS4k that gets closer to that original spec / PC version.
