There are several reasons why PS3 PKG files cannot be installed on the PS4:
In the image creation settings, use the standard 32-character passcode ( 00000000000000000000000000000000 ) used universally for community-built Fake PKGs.
Moreover, PS3 emulation is that eat up CPU cycles. The PS4’s Jaguar cores (1.6 GHz) are simply too weak for real-time PowerPC-to-x86 translation. Even Sony’s own PS3 cloud streaming (PlayStation Now) ran on custom server blades with Cell processors, not emulation.
Because of this fundamental difference, a PS4 cannot read or execute the code inside a standard PS3 PKG file. To make a PS3 game run on a PS4 via a PKG file, the game must be re-packaged using official emulation wrappers or structural conversion tools. Essential Prerequisites ps3 to ps4 pkg install

When a user chose to install a game or application, the PS3 would verify the package's integrity, extract its contents, and install it to the console's hard drive. The PS3's .pkg installation process was relatively simple, with minimal user interaction required.
Many PS3 classics have been natively ported to PS4: Even Sony’s own PS3 cloud streaming (PlayStation Now)
The PS4 completely dropped the complex Cell processor architecture of the PS3. It lacks the physical hardware necessary to read PS3 game code.
