But as long as the paint density doesn’t match the body density then these arguments still apply…it’s just a difference of the degree of bias

don’t most die have painted dots nowadays?

and note that any three orthogonal axes are principal axes for a cube, but for a die it’s not clear that the principal axes aren’t substantially different from the x-, y- and z- axes. But it seems likely that they are close to them: see, e.g.

The key ideas of this post hold either way, though.
