Thought it might be visually useful to show the effects of M1 (full D50 w uV) and M2 (D50, uV cut) profiles printing a neutral tone curve from L=5 to L=100 with a high OBA paper.
This is Costco Glossy paper which has a large amount of OBAs. The paper white under M2 is LAB (95,-1,-2) while under M1 it is LAB(95,1,-12) for a b* shift of -10. For comparison Epson Prem. Glossy only has a b* shift of -2 which comes from the fluorescence of the substrate, not OBAs in the coating.
The 4 images are as seen under D50 without uV. The top-left image(1) is Rel. Col. using an M2 Profile. The bottom-left image(2) is also Rel. Col. but using an M1 Profile made with full D50 uV. Notice how close they are to each other in spite of the large difference in M1/2 white points from OBAs. But if looked at closely, or sampled with the eyedropper, the bottom neutral curve is slightly bluer by 1-2 dE.
Basically, using Rel. Col, (or Perceptual) there is not much difference between using a M1 or M0 profile and an M2 profile to print. This is because these intents are scaled off the media's white point so everything is adjusted to LAB(100,0,0) being mapped to that white point.
However.Abs. Col. intent is another matter entirely. If you print LAB(50,0,0) then you should measure LAB(50,0,0) within system tolerances. If the color can't be printed, as is the case when you ask to print LAB(100,0,0), it will print the closest color and it will do so based on being illuminated with D50 (uv cut - M2) or (full uV D50 - M1). Since the uV increases the spectral response at the bluer wavelengths, attempting to print LAB(100,0,0) will lay down significant yellow ink to bring the b* towards 0 and counteract the uV induced blues.
The top-right image(3) is how the image would print using the M2 profile. The printed tone curve is neutral until the gamut edge is reached (L*=95). This is because the profile was made with M2 (uV cut D50). It's slightly warmer than the images on the left because it is a completely neutral gray while the Rel. Col. images scale from media white which is very slightly bluish for the Costco glossy under uV cut D50.
The bottom-right image, made with a M1 profile, requires much more yellow ink to bring b* from -12 to 0 because this printed image is designed to be viewed in a fully compliant D50 booth or outdoors, under daylight, with high levels of uV. The result is that it looks pretty awful with no uV. But it would look fine outside. It also measures neutral using an M1 spectrophotometer.
