It's funny when you play older games with things on the loading screen you only see them for a split second nowadays.

I played Bayonetta for the first time a few months ago on my steam deck, and during loading times you were able to practice combos and stuff. Unfortunately it only lasted for a split second since it loads so fast from the SSD, I'm guessing it's original release on console disc allowed players a bit more time to try it while it was loading from the disc.

You can still hit a button to stop the loading from finishing, IIRC, and then just hang around on the combo practice screen as long as you like.
