Assume LV manual focus gives best focus for Cam/Lens/FL/Aper/Illum.

YMMV, but I wouldn't trust LV manual focus. I find that it is not as accurate as one could hope. I think it better to take a shot and enlarge it in playback (or Lightroom tethered). Delete the image if it isn't right and try again. Tedious, but because of the poor quality of LV, I think it would be more reliable for critical focus.

BTW, I find LV CDAF to be less reliable than PDAF on my D800E.

What can give the photographer a better example of the optimum focus than focus on the sensor itself.

Having a better quality Live View. With line-skipping and noise (especially in low light) I find LV on the camera LCD to be less than ideal. I've done a number of shots where PDAF produced a better focus than I could manually focus in LV with medium magnification (full magnification being beyond 100% and often unusable).
