A few days ago, I put in a platform request for this, and it's now been approved. This affects a lot more than just my games, so I figured a public mention would be a good idea. It's maybe a bit wordy :P but with many PS4 games getting proper PS5 releases (Death Stranding, Control, Ghost of Tsushima, FF7 Remake, not to mention several from around launch like SpiderMan Miles Morales and Immortals Fenyx Rising), this allows for distinction between runs of the PS4 version done on a PS5, and runs of the actual PS5 version.

Use at your liberty. Just wanted you all to know it's there :)
