they have started taking pictures on delivery as well as a signature so DNA doesn't seem viable.

A signature Is useless. Anyone could've scribbled their name, even the driver himself- which I continue to personally experience.

In terms of photos, what part of the home does the carrier driver tend to capture?

More often then not the package on my doorstep and the open door, both of which are unique. I have Se'd the same currier in the past successfully for missing item method but I had phone calls and knocks at the door and that was just for a £50 item. This item is to heavy for missing item. I don't know how the items are sent out either so feel wrong item (with a the cheapest tablet they offer) may be completely rumbled.
