No, it's a measure of brightness. ;-)

When you refer to whiteness, are you talking about whiteness versus
grayness, or whiteness versus some color cast? If the former, 93 is
certainly a bit better than 90. If the latter, you might be able to figure
it out if you have some software that lets you see the numeric white point
of the paper's profile: smaller a and b values indicate greater neutrality.
