My humble understanding, speaking with some people more competent than me on the matter, is that the M1 difference begins to matter when a printing substrate exhibits some degree of fluorescence. If a substrate contains little or no OBs, like a sheet of Epson Proofing Standard 240 or a sheet of good-old newsprint paper, then there will not be any difference, in my experience, between M0 and M1 measurements and "traditional" instruments can continue to be used safely, even though the relevant standard printing condition is referenced to M1. See?
It was repeated many times on this list, by Martin Open and others, that "matching the level of fluorescence" between a given proofing substrate and a printing substrate was the key to color predictability. Before ISO-13655:2009, I remained sceptical of this approach. But today with M1 measurements, which, to my knowledge, expose the substrate to a higher degree of UV content, this approach to me starts to make conceptual sense.
Suppose my offset printer uses brand X coated paper. Suppose further that this paper incorporates some degree of optical brightening, as most printing papers do nowadays. In theory, using M1 measurements, it should be possible to derive useful information about the characteristics of this coated paper which could be used as a guide for selecting the optimal proofing substrate, or even to successfully modify one of the ISO-15339 reference printing conditions characterized datasets, to generate custom proofing for this very printing substrate.
I think the possibilities are interesting. I wish more software would allow advanced use of this new M0 vs M1 vs M2 measurements.

But is there anything always different between M0 and M1? Would legacy instruments that produce M0 actually differ in all cases (they might, but might they not)? One is UV included, on is said to be D50 UV included.
