For now then they are indeed flying a D1 equipped 757. However KEF normally only gets non-D1 equipped 757s. It looks like they upgraded JFK-KEF for this summer/early Fall. However next year's schedule does show non-D1 757 equipped flights.
If DL runs short of equipment, (IRROPS, etc) JFK-KEF will likely be the 1st downgraded. Nothing really different from JFK-SEA that alternates between D1 and First Class. The main difference being SEA gets D1 more often than KEF.
