No need to remove the splash screen during boot...
Just hit ESC and you can see what is behind the splash screen...

"nomodeset" simply enables Usermode display drivers, the "old" way graphics drivers were run before nowadays when display drivers run in kernel mode by default.
Running in kernel mode probably has some theoretical performance and security benefits, but I doubt that there is any significant actual downside... at least AFAIK.
