A launch screen is intentionally boring

Source: iOS Human Interface Guidelines, Apple
If you think that following these guidelines will
result in a plain, boring launch image, you’re right.
Remember, the launch image doesn’t provide you
with an opportunity for artistic expression. It’s
solely intended to enhance the user’s perception of
your app as quick to launch and immediately
ready for use.
