Lighroom Classic and Contrast Slider on Import

I recently experimente with B/W photography. Thus I have set the camera to produce B/W previews with high contrast and clarity. After the import, I noticed that the contrast slider is way higher than it usually is. I have a preset applied, but it does not change the development settings, only camera corrections and default sharpening and denoising. Investigating a bit more, I found that Lightroom does often change the contrast slider to some value by its choice, also without the B/W setting in camera.

So, the question is: When would Lightroom set a contrast value? Is that part of the default Adobe profile or what?
