It may be because there is very little K in the prints.  Depending on
the image and the curves, it's possible that K is only introduced in a
quantity sufficient to tell a difference in the lowest zones.  For
example, when using UT7 with sliders, I discovered that there is no K
at all until about RGB 5, or about 98%, and it isn't pure K until RGB
0, maybe 1.  So it's possible that something similar is going on
there.  It may require a low key image before the difference is
noticeable.  In BO printing, which is all pure K, there is an
immediately apparent difference.
