I found the enhanced night vision to add a bit of noise to the images in low light. I think it has something to do with the motion. As you can see in the linked videos, when the enhanced night vision is on the rear camera seems to be slightly noisier. I really didn't see any difference in the front camera. Both videos were shot within a few minutes of each other on approximately the same place on a rural road. But I did find the enhanced night vision to be helpful in Parking mode. Luckily this isn't an all or nothing setting; you can enable it all the time or only in parking mode. I recommend the later.
