I have the same issue: When closed, there are overhead sounds if the road isn't perfectly smooth. My understanding is that this is a fault common to panoramic glass roofs; watch: <https://www.motoringbox.com/cars/your-car/6-reasons-to-avoid-a-panoramic-roof/> I special ordered my Trofeo White Ti Sport with this option as it's parked in the sun all day and this feature would facilitate hot air escaping thus keeping the interior somewhat cooler than it otherwise would be.
While I doubt this is an engineering or assembly defect per se, my educated guess is that the amplitude of flex of one very long part (bear in mind the massive size of this thing) is greater than the gap between an adjacent part and thus comes in contact with the second one on occasion. The noise is not the type of rattle I would expect if something were loose.
Other than that, are you enjoying the car's almost telepathic response to driver input ... acceleration, steering, braking?
