Micro Displacement Material Preview
I suggest having a scalar value/ factor which you can modify in the material preview mainly for materials that use micro displacement. The material preview can be so distorted and look unnatural.

Maybe the material preview could be a pop up that you could make big then close when finished viewing the material. It does need its own scale parameters, for the preview objects, to visualize correctly.
The material preview has needed some work for years. Speaking for myself, the previews rarely show anything truly useful for pbr work at a scale that helps a lot. But flexibility of view is a big loss as well, eg the partial cube view that's darker etc.
