ARKit Face Tracking not supported on iOS 14 with iPhone 8?

Issue ID: FB9081158

Quoting documentation of ARFaceTrackingConfiguration:
https://developer.apple.com/documentation/arkit/arfacetrackingconfiguration

Face tracking supports devices with Apple Neural Engine in iOS 14 and iPadOS 14 and requires a device with a TrueDepth camera on iOS 13 and iPadOS 13 and earlier. 

But when I try to run the official sample app on iPhone 8 running iOS 14.4.2, the app reports that ARFaceTrackingConfiguration.isSupported is false.

If I am not mistaken, iPhone 8 has Neural Engine. Is this a known issue?


I'm pretty sure the iPhone 8 doesn't have a TrueDepth camera.
iphone SE doesnt have true depth, Face Tracking works.
