Interestingly enough, while doing a bit more testing, I just found out that, if you hit keys on the keyboard during early boot (before Plymouth shows up), you can get the prompt to show up. Both Kinetic and Jammy behave the same way. I'm typing slowly but continually during the whole entire early bootup. If I don't do this, I get a black screen.
Also, both Jammy and Kinetic display their splash screens properly during shutdown.
