I think the size is the same.
But the scans will be distorted. That means if you align several single scans you will notice that they do not fit to each other.

I don't know if you have the possibility to „tell“ DAVID in the Advanced Settings that your corner is 100° and not 90°.

yes , I dont use advance setting tell DAVID the degree is not 90,I just want to know if the corner is not right 90 degree.what happen? in my viewpoint ,I think the scan is distorted,but what distort?
it is narrow ?or fat?in my point ,the tall size is not distorted,but the horizontal direction must be longer or shorter,so the scan must be fatter or more narrow.
