I've followed the instructions in the WWDC23 presentation entitled "Support HDR images in your app" (wwdc2023-10181), but I am unable to see any HDR effect with my test photos. The Apple photos app shows the photos with the "HDR" tag and has the HDR effect. Has anyone else been able to replicate what was done in the presentation in their app? Is this truly supported by iOS 17 on an iPhone 13 pro with Xcode 15.0 beta? Or do we need to wait for the next beta release of iOS/Xcode? Or is there some missing information from the presentation?
