Yes, in Europe all slabbed coins that are MS-62/63/64/65 are graded as fast stempelglanz/ about UNC/ qFDC Kunker even graded some MS-66 examples as fast stempelglanz! We have a Canadian TPG named "CCCS" tat grades in European style.
You are correct, as I stated, based on the images provided we can't be assured of an under/over-grade condition. Just based on my experience, having viewed thousands of Liberty Eagle images, I just picked a current random auction superior? coin. I'd bet that the condition of his coin is equivalent or superior to the following coin, 2 grades advanced?
