Dampers reduce/dampen crank angular and torsional vibration, they do not balance and out of balance motor condition. The CV is created by the firing order, cyl pressure and curve, etc. Its like a shock absorber acts on a spring--doesn't disallow/stop the movement, it just controls it. I cannot see where a properly balanced rotating assy would have any negative impact on how a properly operating damper works ,unless it some how created a resonance condition that could actually be felt.
In our belt tensioner business, we deal with CV management everyday. For example, CV on modern big truck engines is getting worse as the smaller displacement engines (12L for example) are driven across a wide performance curve and torque curves are lowered to gain fuel economy and further manage emissions. In turn, it makes it harder to manage everything attached to the crank.
Comparing all engine designs, the V8 (V engines in general) has the least amount of CV, then 6s , then 4 cylinders.
