ReplayKit is supported on newer devices (iPhone 5S and later), running at least iOS 9. However, on devices that don't support ReplayKit (like iPhone 5) and run at least iOS 9, UnityEngine.Apple.ReplayKit.APIAvailable returns 'true'.

Steps to reproduce:
1) Open the latest attached project.
2) Build for iOS.
3) Deploy on an iOS device that doesn't have ReplayKit support, but runs iOS 9 or higher.

"ReplayKit is available" is logged in the Console (meaning that ReplayKit.APIAvailable returned 'true'). This doesn't occur if iOS version is older than iOS 9.

Reproduced on:
5.5.0b2, 5.4.0f3
