Simply show me one that doesn't.

White and/or black points applied?  ALL 8 bit images have the setpoints
applied, unless you have some weird/old scanner that only provides 8 bit
data!

Not only do I not believe you, I know what you're saying is wrong.  Again,
if someone here really wanted to shut me up about this, then provide an
image...no one has...or can.

Yes, simple snapshots with my Hasselblads...the ultimate P&S...or simply
that the "problem" doesn't exist ;-)

If you require extreme tonal curve manipulation, then I suggest you look at
getting the image "right" on film, instead of relying on your image editing
program to get it right for you after the fact.  Of course, there are some
instances where this is not possible/practical.
