Help
I did the manual search that barmar suggested. On the first 50 hands where 3NT could be set, the "normal conventional lead" (you'd have to trust my judgement on this) would be best 38 times. Note that this does not mean that on 12 out of 50 hands 3NT would not be down, it could still be down but fewer tricks. I would rather see the leads that beat the contract being highlighted, but unfortunately I think that DMP doesn't do that. I checked a few hands though and on those hands it was the same.

OK, that is interesting. Can you have a quick look through the hands and tell us what distinguishes the 3NT ones from the 4H ones?
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn

When single-dummy simulations are a lot better, and we can input our individual styles in detail, we will get nearer some kind of proof. Until then the results are very interesting

It does that.
You just have to choose exact contract instead of amount of tricks to take in given suit/NT before calcs are done.
Then when you browse the hands it doesn't highlights any leads on hands when contract makes and highlights winning leads on hands when contract doesn't make.
