The fact that the model recreated the interior dome pattern is concerning and makes me think this didn't test what they think. The interior dome pattern isn't visible in either picture. So it took the picture, and the name, then either via search or training data, knew that there should be an interior pattern. So it could be getting information on the pantheons dimensions or existing models. Whereas other models might be building based purely on what is seen in the reference pictures.
