Always. I did not find an option to avoid the interpolation or
change the type of interpolation.
See sampleindex 10559 to 10560 for an example. (attached picture)

The real sampled values:
options->settings->colors->digital waveform
The interpolated waveform:
options->settings->colors->analog waveform
