For many works, even the best photographs don't entirely capture the physical object - particularly those where texture, including brush strokes is important. Many pigments can't be duplicated via the standard printing gamut. This particular work is a woodblock print, so perhaps photography is adequate - I don't know.
I'm not clear that the original artist's materials, with respect to longevity is really relevant, assuming the artist didn't explicitly intend it to be ephemeral.
