When I want to apply a visual analysis (Zebra, Environment map or Curvature analysis) on a SubD model, its wires and control points get visible through the geometry, which is extremely intrusive and does not allow to closely examine the reflections and surface quality. Adjusting the control points this way is not user-friendly at all. 
Could this be fixed in future updates, by adding an option to turn off or on the see-through visibility of the control points and wires?
have you tried CullControlPolygon?
I don’t use it, because it hides many of the visible control points and control polygons. Also, even after using “CullControlPolygon”, the wires at the opposite side of the model are still visible while using Zebra or other kind of a visual analysis, leading to distraction and inability to properly see the zebra stripes or the fake “reflections” of the environment map. The problem with see-though geometry happens only if Zebra, Environment map or Curvature analysis is being activated.
I have the same problem.
Hope this can be fixed.

When someone wants to analyze the surface quality, he or she needs to see clean zebra stripes or environment map, without an intrusive x-ray rendering of the geometry and hundreds or thousands of control points, edge wires and control polygons far away behind the nearby surface.
I now see that the subs edges on backside are only visible when the control points are on. Probably that part needs to be fixed. If however you want to focus on zebra, do you really need to see any edges at all? Otherwise you can tick those off in the zebra options
Zebra analysis, Curvature analysis and Environment map all have an optional tick to turn on/off the wires. Visible wires on the geometry could be helpful, but only if it’s rendered on the visible portion of the geometry (like what you normally see without the analysis tools). However, SubD geometry and control points seem to ignore the rules of the display models and are always rendered in X-Ray display mode while using those analysis tools. The logic is that if someone really wants to see see-through X-Ray geometry and control points everywhere, then he or she could simply switch to the dedicated X-Ray display mode. 
To answer your question, visible wires while using a visual analysis tool helps to determine the shape of the geometry, especially while point editing the surface meantime.
