If that was actually the case, then technically it is correct for the
book to not colorimetrically match the originals - an appearance adjustment
has been made to allow for different viewing conditions. What's interesting
is whether that appearance adjustment was made empirically, or in accordance
with an appearance model.
It's also interesting that if preservation considerations mean that a very
much lower light level is being used to display the original works than was
used by the artist when creating them, then in fact an appearance adjusted
reproduction may be truer to the original intention that the works themselves
as exhibited.
[This brings to mind an experience I had recently viewing an exhibition
of (mainly) clothing, where the light levels were set very low.

Rather that using lower wattage lights, the curators had simply dimmed down
their usual incandescent lamps to extreme levels. The resulting "white" point
was very, very red, and that combined with the very low light levels
meant that adaptation to the white point was extremely slow and incomplete.
The result was exceptionally poor color rendering. In fact they knew they
had a problem because there were signs basically saying "don't complain
about it - we have to do it". I don't know whether to be surprised or not
that the curators of a regional museum would appear to be so ignorant of
lighting technology and its interaction with human vision.]
