Controlling when splash screen disappears

Hi all,
as we all know you can setup a splash screen using the player settings. This image disappears automatically when Unity and the first scene is loaded.

And that's the problem. Because we only load a simple scene and after that we start to load our assetbundles etc. dynamically. During this process the splash screen should still be visible and we want to decide when the app really has finished loading and disable the splash screen.

Can this be achieved somehow?

 

Try this...

go to 2 mins 44 and pause

 

I would prefere to control the native loading screen.

But thanks anyway
