I did a quick search and the only reference I found was in an article from Inside Flyer website concerning the introduction of the new central screening back in 2015. At the bottom of the article there is a mention of the new Pre Departure Clearance points:
https://insideflyer.nl/schiphol-central-security/ . According to the article it is only people on US Carriers that have to go there I was directed there as my flights were operated by
Delta albeit with a KL flight number? It may have changed as my last flight to the US via AMS was early this year.
