At the same speed, you are DEFINITELY burning more calories on an incline. Compare walking on a flat road to walking up a hill!
I DO NOT run, so to get a good workout on the treadmill I crank up the incline. I have a heart rate monitor so I don't need to rely on the handbar sensors, and I push to get it up there. I walk faster on the treadmill than in real life, haha.
As for calories burned ALL NUMBERS YOU GET ARE ESTIMATES regardless of the source. The best estimates will be from a decent quality heart rate monitor, and I find that the few times I've compared numbers, the caloriesperhour.com calculated number is fairly close to my HRM. As for the machine numbers, RECENTLY, they have been close to my HRM, but I am very close to the weights they are generally calibrated to (around 150 I believe) so if I set it for 140lbs, I'm going to get a much more accurate ESTIMATE than someone who weights 250 (like I used to).
