It's a good suggestion to "hard proof" some critical images like this before jumping right into the "big thing". Such dark tones are a challenge, I wouldn't rely on "soft proofs" here. Also consider the viewing circumstances of the actual coffee table book. I bet nobody will look at it unter controlled D50 light or something. Or under a real bright light that might show the last detail in the shadow. Rather one would be sitting in a comfy chair with a dim, warm light ... but perhaps you considered all that, just thinking aloud. ;-)
