iPhone 15 Pro Dark shadow when taking photo's in a bright area

I have had my iPhone 15 Pro for a week or two and I have to take pictures as part of my job. I upgraded from an iPhone 11, and was really looking forward to the improved camera capabilities in this phone. I take photos in a room that uses full spectrum lights, so it is really bright, and since it's full spectrum, there aren't the same color distortion problems presented by fluorescent bulbs. However, I have discovered that my phone almost always sticks a very dark 'shadow' either down the middle of the photo or on the sides of the item being photographed. As I change the zoom, the shadow moves based on the zoom, until I fully zoom out to wide angle, then the shadow disappears. I have attached 2 photographs, each a different zoom amount. The photo's even look dark, but trust me, that room is VERY brightly lit and there are no shadows on that wall.

I'm tempted to take it to the Apple store and ask them, but thought I'd start here.

Thanks.
