The LaunchImage was definitely about perceived launch time of an app. The idea is you show an image that was similar to the main screen of your app and once the UI initialized it would just magically swap that for the static LaunchImage. So you'd want a really fast PNG decoder to be able to get it on screen and let the CPU do the work of initializing the application.
