UIImage's withTintColor and dark mode

I'm trying to use UIImage's new withTintColor method to update images for dark mode. So far, it only works when using UIButton but not UIImageView nor CALayer.

As far as I can tell, accessing the cgImage never returns a tinted image. I also can't find an API on UIImage to see if it was created with a tint color. Is there an API I'm missing?

This is what I've tried so far:

    let dynamicColor = UIColor(dynamicProvider: { (traitCollection) -> UIColor in
        if traitCollection.userInterfaceStyle == .dark {
            return UIColor.white
        } else {
            return UIColor.black
        }
    })

    let pinkImage = #imageLiteral(resourceName: "PinkImage")
    let hopefullyDynamicImage = pinkImage.withTintColor(dynamicColor, renderingMode: .alwaysOriginal)

    // This UIButton properly shows a black or white image depending on dark mode. It automatically updates
    someButton.setImage(hopefullyDynamicImage, for: .normal)

    // This UIImageView shows either white or black image, but it doesn't update when the dark mode is switched on or off. It is stuck in time
    someImageView.image = hopefullyDynamicImage

    // This CALayer shows up as pink. The tint had no effect
    someUIView.layer.contents = hopefullyDynamicImage.cgImage

I've also tried using UIImageConfiguration like this, but it still has no tint in the cgImage:

    override func traitCollectionDidChange(_ previousTraitCollection: UITraitCollection?) {
        // This layer still shows no tint color. It is the original pink
        someUIView.layer.contents = hopefullyDynamicImage?.withConfiguration(self.traitCollection.imageConfiguration).cgImage
    }
