I'm not sure what you mean by that Ian, are you saying that LR's histogram is not accurate or most exposures are not accurate?
I usually find that when using just the highlight slider on any program you can usually recover a third of a stop before it starts effecting other tones in the image.
The example I tested was what I consider a good exposure in not overly bright conditions with the brightest part of the fur 1/3 of a stop underexposed but no fur detail was showing before adjustment.
Just using the Highlight slider to recover the white fur and the resulting tones in the rest of the image.
The same with Capture One 6 , in this case more detail was recoverable but to the detriment of image saturation.
Now in Silkpixy Pro the highlight slider has no visable effect at all on highlight detail and is about as much use as a chocolate teapot..But look what happens when you just reduce overall exposure.
Now i know there are other adjustment you can make but this was just to test the Highlight slider in all 3 programs, personally I think these sliders are overated.
