Device fails to render icons as they appear in Icon Composer

This app icon features multiple layers with the blend mode set to Screen. iOS fails to render these despite looking perfectly fine in Icon Composer.

This is unacceptable. How can a designer build an icon if they can't rely on it being displayed like the preview on a device?
