You got a very "interesting" history there, it certainly not particularly grounded in reality however.
PS3s edge was generally seen as the DVD player.
That's why Sony went with Blue Ray in the PS4, hoping to capitalize on the next medium, too. While that bet didn't pay out, Xbox kinda self destructed, consequently making them the dominant player any way.
Finally:
> PS5 has been practical, it's just the technology/approach ended up adopted by everyone, so it lost its novelty later on.
PS5 did not have any novel approach that was consequently adopted by others. The only thing "novel" in the current generation is frame generation, and that was already being pushed for years by the time Sony jumped on that bandwagon.
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.
