Is there any way to make the login screen from a locked session (either by using Ctrl+Alt+L or from a screen timeout) look like the login screen when you're starting a new session? I hate that everything on the lock screen aside from the password input is black.

However, you can use a theme for the lock screen. There are quite a few available at gnome-look.org. Here's an example.
