Yes. And I might add that they put that heat resistant underlayment on and the attic is much cooler.

They are supposedly lifetime shingles and warranted to not have mold or mildew blackening.

Ventillation is not correct. Power ventillator fans and a ridge vents do not go together. When the fan is operating, fresh air will be drawn in through the ridge vent and out the fan instead of the soffit vents which hopefully you have.
