I do have an SDS, but it is a Battle Spec, openly claimed not to be from any original molds. It is their (supposedly) stylized, cleaned up product. And, it is dimple-less.
The SDS comparison should technically be made to their Stunt helmet. If anyone has one of those, it could be checked.
A quick visit to the sds website shows closeups that are somewhat inconclusive imo (if I had to guess from the pics I'd say they aren't there):
