NLWC have done well at Worlds no doubt but not so much in the Olympics. Obviously we know what happened this year as all 4 entries underperformed expectations but in 2020/21 they also sent 3 guy and only DT took home the gold. Not saying that was a bad result necessarily though.
So to your question...yes, but I would say that in general to any situation when there is such a heavy concentration at one club.
