If that was an issue why would they have started serving the route in the first place? The real reason is that AMS is slot restricted, and KLM obviously needed to cut some routes to make room for some new ones. KLM cityhopper are also short on aircraft I believe. I am sure they would continue to serve the route quite happily otherwise.
