CaptureSample App doesn't get depth data on iPhone12 Pro Max

As for the subject, CaptureSample App doesn't get depth data on iPhone12 Pro Max. I mean, the app reports that we correctly have depth data and photos captured are shown with depth data green badge attached but generated .tif files are always a full white file, no more details. Is there something i'm missing? Do i need to do something more to enable depth data acquisition? I'm taking pictures of objects no more distant than 50 cm
