Not according to the Schiphol Approach controller I talked to some days ago. He referred to the general rule of always having to mention the station being called on first contact. "Callsign only", in his view, refers to the actual message being broadcasted to the receiving station, not to the station identification. In this example that would be the part coming after "Schiphol Approach": "Schiphol Approach, <callsign>".
Next time I'll ask again, just to be sure.
