Gray haze on DNG photo iPhone 15 Pro Max running Tahoe 26.0.1

When I open a DNG file in ProRAW format taken with an iPhone 15 Pro Max, a gray tint appears on the full-screen preview. I also have an Intel iMac running Catalina and have no problems. I've attached three files to show the preview progression. In the Photos app, it looks fine, but with another app like Affinity Photo, the DNG photos are very dark, as seen in the preview. The gray tint appears more or less quickly depending on the size of the photo. The photos are from a screen recording.
