Nikon has improved this in newer models by using diffusor, but older models had very poor quality of scanning B&W materials. The problem was that LEDs emit directional light, which had problems passing through particles of silver halides. That was never a problem for scanners with diffused fluorescent light, like Minoltas. I remember test of optical density of film scanners. And while Nikons performed great (Dmax around 3.6) when scanning slide and negative film, Dmax dropped drastically to somewhere around 2 in case of classic B&W films. And that's exactly my experience when I used Coolscan III. AFAIK only medium format Nikon's scanners (8000 and 9000) use rod dispersion LED technology, that creates more diffused light to achieve good results when scanning B&W films.
