First, I agree that blown highlights can just be another way to show the

of a bright sky in a corner of a backlit building almost filling the 
picture: the histogram could well describe the light distribution within 
the backlit building and you'll be fooled by a perfect histogram missing 
the sky (far right, outside the histogram scale).

I thought that the histogram was generated from every pixel of the JPEG 
image generated by the camera?  (PEF RAW files contain such an image 
too).  I don't see how it can "miss bits".
