Can we load during the Unity splash screen?

Trying to decide if I’m gonna go pro or free, was just curious - can we at least start loading while the splash screen is being displayed? Or are we locked out during that time? And how long is it? Only at the beginning?

Thanks for any info

It’s already loading when the splash screen is displayed; it never just sits there doing nothing.

Ok, so even after the Unity core files load, if I start building a complex scene/loading lots of models etc… that will all take place behind the splash screen?
