the DC component in the spectrum plot is the big green "spike" at 1 Hz on Span (usually @ 0 Hz on an analyzer with enough resolution).
everything else is harmonics/aliasing.

basically, by processing a waveform asymmetrically via saturation/compression (non linear efx), you create a DC offset.
that is what the spectrum plot shows...adding the "warmth" (ie...even harmonics) also adds a DC offset the output.
