Question: Does Unity 2018 LTS adhere to Apple Storyboard Launch Screen Automatically?

I see there is an option for a "Use Storyboard for Launch" checkbox in the build settings that allows for a custom storyboard, but does Unity 2018.4.26f1 LTS automatically make a storyboard launch screen for you?

I am using the Splash screen settings for my startup logo and my xCode build looks to have storyboard files in it. When I launch my game, everything looks correct, I just don't know if it's using the storyboard.

FWIW, the upload succeeds to go to the App Store for TestFlight. I don't know if that means it will pass Apple requirements for production though.
