Less likely to get a refinished arsenal refurb in my eyes

Don't have this expectation. The CMP specifically says most have been rebuilt, sometimes multiple times. Whatever the criteria is, the CMP is assessing conditions. There is apparently some overlap when it comes to a higher end field grade and lower end service grade and grading is always somewhat subjective to begin with.
There have been some rack grades that are more beat up but claimed to have the original finish and there are some very nice looking service grades that are nice because they have been refinished.
Sometimes there are color mismatches of the slide/frame but very little wear. Sometimes the color is consistent and even looks very nice, but more heavy sand blasting has been done and edges more rounded or lettering worn away. Looking at pictures online may be a little misleading.
A lot of people get caught up with the whole idea of the slide and frame manufacturer matching. Often that Remington Rand frame and Remington Rand slide (or Colt or whatever) one gets don't really match since there were different versions of slides through production. In addition to that, the barrel, grips and small parts will often be mismatched even if you get lucky enough to get a "matching" frame and slide. Even if that frame and slide combo are of the same correct era, finishing may not match depending on how and when rebuilding was done.
It does feel good to say the frame and slide match and to most this is preferable. The part that shows the name of the manufacturer is only on the slide and one has to have a minimal understanding of the frame markings to know what frame it is. To some, that Union Switch and Signal slide on the Remington Rand frame might look a little more impressive.
If you came across a rebuilt 1911 with a Colt/Remington/US&S/Ithaca frame with a Singer slide (no you won't get one like this from the CMP) it would certainly not be Singer, but most would find it very desireable.
