If noise reduction artefacts aren't going to kill you, neither will some dirt. 

It's a no win battle. Small amount of noise reduction, takes off some of the major dirt and softness problems. Only complete restoration will remove the whole lot. But what producer can afford this? Especially for archival material.

Personally, I don't like the artefacts. It looks odd. Dirt is acceptable to "the average viewer". If they see pixillation  of quick movement or other strange DVNR  effects, they think there is something wrong, can't work out what it is, so the picture looks bad.

None of us like dirt. But? It's then up to the producer to sell his product and overcome any criticism from any QC facility.

Good luck
