A few years back a Simple Shooting Gallery Game sample PKG for PS4 TestKit owners surfaced, and recently ThatGuyNamedJoey reported a curious PXG4: PS4 Full Game Standard Disc Game Test 4 (Prod) listing for Whale Whale Whale: What Do We Have Here? (80.22 MB) by WILD SWANS on PlayStation Store (Cached Page) at $0.49 that appears to be a Sony marketing tool used for early server development and upgrade integration testing with PS4 / PS5 titles based on the description. 
PXG4 PS4 FG Disc Game Test 4 Entitlement (CUSA24837 Prod) PKG Leak
Elusive like the PS4 IDU (Interface Demonstration Unit) Utility, ThatGuyNamedJoey shared this image for reference with poklane pointing out the comical CUSA24837 background.
Needless to say, the mysterious application has since been removed leaving only an "Unable to Find This Page: It may be unavailable or the address may be incorrect. Select [Home] to continue browsing the PlayStation Store." default error template in its place.
However, before it was taken down YaboyPS5 (aka Minecraft, FNAF, AndMore on YouTube) had the foresight to capture a demo video of it in action below! (PS4_and_PS5_store.mp4 - 82.93 MB mirror in case $ony removes the YouTube demo)
PS4 and PS5 store????
I found this on the PlayStation store on August 24 2020 its called "PXG4: PS4 Full Game Standard Disk Game Test 4 (Prod)"
