Sharp reflections despite material smoothness?

Hi, I was wondering if it would be possible to make Reflection Probe reflections less blurred than point-light specularity. High material smoothness means very crisp reflections, but glitchy point-light specularity. Would it be possible to have reflections be less blurred but not too pixelated and under-interpolated? Normal maps to a great job distorting low-res reflections already.

Also as a side note: Would it be possible to disable lighting glossiness on the standard shader? Specular setup doesn't get rid of lighting specularity entirely.
