Nikon USA has quite nice sample images from the DL 24-85. The contrast, colour and flare resistance seem exemplary and in my perception the images look far better than samples from Nikon 1 cameras. Since it seems the camera has been test used to get those samples, it would seem it does work but perhaps there is a reliability issue. I hope they solve the problems soon, the images look that nice.
It would be nice if Nikon would also not release software products with significant problems, but they do.
