So I don't have mine yet but with madden there was an option in the drop down next to where it says play and it let you change to the ps5 version or the ps4 version and would offer the download if you didn't have it. If you installed from the disc my guess is it defaulted to the ps4 version.
Like I said, I have to install mine still as I am still at work but I know that is how madden worked.
