Use '#' to define display in login screen seems changed. You might need to
change this to "chrome://oobe/app-launch-splash" and update kKnownDisplayTypes
in oobe_ui.cc.

See https://chromiumcodereview.appspot.com/21004005

Done. I added the app launch splash screen as a display type that loads assets
from the login flow.
