In the event a consoles online services get shut down or the publisher decides to delists the title, if you didn’t install the game fully before this happened your disc will become useless. This situation could potentially be different in that whatever is on disc won’t work unless you go online and download the rest of the code. This means in future when the consoles online services are no longer supported you can install and play a suboptimal version of the game. Most PS5 series X games work this way, so you should be able to install from the disc offline and atleast have a playable ver 1.01 build of the game. Since PS4/Xbone pretty much all games install the content from the disc, then the disc acts as DRM validation when running. I believe PS3/ Xbox 360 installing game disc to hard drive was optional for most games but offered improved performance.
