Yes, that should read 126711CHNR, as the 1 at the end denotes Eveorse Rolesor (stainless steel and Everose gold); a 2 at the end of the reference number would imply that it was a Rolesium model (stainless steel and platinum), which currently only exists in the Yacht-Master range - great catch!
As for the difference in PVD color intensity on the Root Beer bezels, some of it may have to do with the age of the watches. While the BLRO has variations in the ceramic color, which are actual differences in the color of the material itself, the darker color of the Everose gold PVD numerals on older examples may just due to very tiny amounts of dirt, oil, and/or polishing compound stuck to the recessed engraved numerals, since all of the material itself should be the same 18k Everose gold. As these recessed surfaces are not smooth but rather textured, older examples may appear slightly darker simply due to incredibly small amounts of oil or debris stuck to them.
