The usual definition of harmonic distortion is that the output contains harmonics that were not present at the input. Since the lowpass filter attenuates higher frequencies, one would expect the harmonic distortion at high frequencies to be lower than at low frequencies. The low pass filter does phase shift the higher frequencies. If you count that as distortion, then there will be more distortion at the higher frequencies. But, I doubt that Hspice counts phase shift as distortion.
