You've got your history wrong too.
The PS2 was the DVD console. The PS3 was the bluray console.
The PS4 and PS5 are also bluray consoles, however blurays are too slow now so they're just a medium for movies or to download the game from.
You're right, I mixed up the version numbers from memory. I'd contest the statement "the history is wrong" though, that's an extremely minor point to what I was writing.
