Google composites the sparkle as a plain alpha blend: observed = α·overlay + (1−α)·original. Because the overlay colour and its per-pixel alpha are known, that equation is invertible — original = (observed − α·overlay) / (1−α). So the pixels under the mark are recovered exactly, not painted over. An image with no sparkle is returned untouched.
