On the other hand, you can see it for yourself that changing the DC servo opamp affects the sound. So you could say the sound is "op-amp polluted".

The DC servo is an integrator, and runs at (much) less than 1Hz. On the Dynalos that I have built (same circuit as a GS-1, see HeadWize - Project: A Pure Class A Dynamic Headphone Amplifier by Kevin Gilmore), the servo opamps have been socketed, so I can remove them if I wish, or replace them with others. I can't hear them in the circuit, or notice from listening if they are not installed.

I know exactly how the DC servo works and that made me curious how it could be I heard differences between the op-amps. The amp was different from the one you mentioned but there was something changing each time.
