LC 9.6.0 RC1 Splash/Launch Images

What I’ve done for a while is to use a flat color that is the average of the colors in the actual title screen. The splash screen is not around for very long, and with there being lots of different sizes required, a detailed splash screen could possibly take up 50 MB of app side, for the sake of a fraction of a second.

In the best case it feels like the title screen faded into view. In fact, you could do that, quickly fade in from a matching flat background color.
