Why do XBOX Physical games have to have the “Game Disc” label at the bottom?

…and the PlayStation 5 covers don’t? It’s so ugly like obviously there’s a game disc in there that’s why it’s the physical copy. I can understand if SOMETIMES it’s a digital code inside in which case, sure, have the digital code label on the bottom but like majority of physical games are Game discs so why ruin the cover with that?
