Nope. It is possible to see the same NW operated flight show up on nwa.com three times, once with a NW flight number (and NW logo), once with a KL flight number (and KL logo) and once with a DL flight number (and DL logo). The reverse is not true for delta.com.
My fear about using nwa.com was that sometime I would screw up and select an itinerary that included a flight with a KL code in an obscure fare class that might not accrue mileage/MQMs.
