Yes that's interesting aswell, but a slightly broader topic: all the different ways in wich you could have a Game Boy experience. When GBC came along it perfected how GB was played because everything prior to it had issues with shitty visibility. The displays aren't clear to begin with and motions cause blurring so that you can't see what's going on.
But i think nobody cared back then that it perfected GB gameplay. I don't even think Nintendo themselves ever marketed this point.
