Splash Screen and Launch image, best practice

I have a question what is considerd the best practice for Splash screens and iOS. Am i right when i say that a splashscreen and the launch image isn't the same thing? Apple say something in their documentation that the launchimage is not there to advertice or show of fancy graphics. It is there to give the apperence that the app is fast and responsive. If I would put, say my company logo, as a launch image, will apple deny my app for the appstore?

Since I work in unity personal edition, removing the Unity splash screen isn't an option. How do other do it? create a scene load in to a sceen with only an image in it and the loading in to the first "game" scene?
