I have been playing about with Spectraview 4.1.26 and Match 3.6.2 (i1 Pro, SV Reference 2690).
Spectraview uses an L* profiling for contrast whereas Match uses 2.2, and SV uses a neutral black, Match: I assume uses native black.
In both cases, I used D50 and 130cd/m2.
I like the fact that SV gives up the contrast ratio, Match doesn't directly.
I would have expected SV to be the preferred, but if my monitor has the SV profile and I convert an image to the SV working profile on import, then the blacks turn up to grey-black? Why would that be? If I use the Match profile on the monitor and convert an image to the Match working profile then I do NOT lose the greys, there is no apparent change when imported.
(Don't tell me to read your book, I have... and RWCM... and I am still stupid!)
