According to Apple, the Photonic Engine that is designed to enable Deep Fusion earlier in the computational photography process brings at least 2x improvement to all of the camera lenses, but it's hard to see that improvement in full in side by side Night Mode photos from the iPhone 14 Pro Max and iPhone 13 Pro Max.
