In answer to your post I would think not for what you mention may well be similar to those that David has shown and these appear to have the countersink already down at the dome edge level.
Therefore this countersink is already touching the leather of the belt before any peening begins, where as the ones that Jurjen shows in his production the inner edge of the countersink in most cases is just a bit above the bottom edge of these domes.
It may well be only 1mm or 1.5mm above it but this is part of the function of these things where the dome gives as the very gentle peening begins, in most cases the edge of the countersink just reaches the leather when the work of this gentle peening is finished.
