You mean "natural white" without brighteners right?
Well, for me there is only one white (a 100% diffuse
surface and 100% reflective at all wavelenghts, and no OB
of course). No mention of illuminant yet!
Technically, a yellow (whitish) or paper with OB (bluish)
is not white even if perceived as such. But, in practice,
as you know, how a whitish surface is perceived depends on
the illuminant, the scene, and your adaptation to the mix.
...It's just a simple concept that helps people go
beyond the "always calibrate to 6500K Gamma 2.2"
mentality.
Many calibrate their displays for D50 though, for a better
match to their light booth (as per ISO 12646).
... I don't see any disadvantage to a well
calibrated display that improves the print-to-screen
match without reliance on chromatic adaptation.
In fact, you match your display to the chromatic
adaptation your brain did on your paper.
If the technique you suggest works in the context of your
work area, good, but I would not generalize it (I know you
did not say that!) to any environment where you could be
adapted to the surroundings instead of the paper itself
(large light booth walls for example).

You mean "natural white" without brighteners right? If a
person is printing 100% on Moab Entrada Bright White
(for example) then customizing the displays white point
(color and luminance) to match this paper's white helps
the user get a better idea of how the image and it's
highlights will look when printed - does it not? If you
calibrate to match a natural white then an image's
highlights (white shirts and wedding dresses for
example) will appear more yellow onscreen than they will
appear when printed on that paper when both are compared
under the same lighting.
For users that print 100% of the time to photo paper I
encourage them to customize their displays to photo
paper white (which is a little yellow and dull). Etc,
etc. It's just a simple concept that helps people go
beyond the "always calibrate to 6500K Gamma 2.2"
mentality. I don't see any disadvantage to a well
calibrated display that improves the print-to-screen
match without reliance on chromatic adaptation.
