As you are viewing a Special Feature and not an Other Version, I believe the meta data you are seeing - including the HDR flag - is for the movie you are watching, not the Special Feature. Does your display show that it is receiving a 4K HDR image from the K?And - drumroll - the HDR download has HDR of the Extended (see screen grab below.) So something is mislabeled. And I wonder if there's a way to only keep the Extended version on my Strato so as not to take up extra space with both?
