ARFrame.displayTransform(withViewPortSize: Orientation) documentation unclear (or the method behaves incorrectly)

I expected the displayTransform(withViewPortSize: Orientation) method on ARFrame to return a transform which, applied to normalized coordinate (0 to 1.0) inputs would produce output suitable to the viewPort coordinate system. Instead, applying the transform to normalized coordinates produces output which are also normalized. The documentation at https://developer.apple.com/documentation/arkit/arframe/2875711-displaytransform does not make it clear that the transform returned produces normalized output.
