Back in the early days of windows 10, this system never showed the screen. I call it the boot screen because I think it is part of the boot process and not the log or sign in process. My theory is that the difference now is that windows has developed bloat, so way more stuff loads, the whole boot-to-desktop process takes longer and that boot screen which is always available but was unnecessary now is deployed long enough to see.
If I upgrade to the 9800X series sometime, perhaps I can just power on by it again.
