Logo display:
Free -> onscreen
Extra -> startup (the Lite-C logo in the startwindow)
Commercial -> startup (the Lite-C logo in the startwindow)
Pro -> optional (only if you want)

So it´s displayed automatically at startup and / or runtime when it´s requested.
You don´t have to worry about it.
The big splashscreen was required back in A6.
