The Torque curve, as plotted against engine RPM, is not accurate in the sense that the engine is not actually at the RPM indicated on the chart but I wouldn't go as far as "artificially inflating..." That RPM scale is calculated from the roller speed. As soon as you step on the gas, the engine will speed up to the stall speed and the wheels has to "catch up". The calculated RPM will be less than the actual engine speed.
That being said, the torque curve, as shown, does give an indication of the acceleration that you would feel. Imagine if you were blindfolded and didn't know the car had an automatic, would it feel like a lot of "low end" torque?
I made some plots and stuff that covers this:
