There´s always some sort of wave modification due to the electronic components.
You can see it quite good when you hook the oscilloscope after a filter. Even if the filter is fully open, there´s a modification of the waveform. Same with VCAs etc... the more direct the path between VCO and oscilloscope the more accurate the result is.
