Digital BW, The Print

And presumably, limiting all of this is the eye¹s ability to discern a
difference in luminance.  Of course everyone¹s eyes are different but one
could estimate an average ability to discern a difference in L* (with a nice
normal distribution around that?).  I remember a debate here as to whether
one could see a 1 L* difference.  Even if we agree we can see a difference
of 0.5 L* (nicely printed in reasonable-sized patches), most matte paper
could only print c166 discernible shades of grey.
