no, by the definitions you cite, the variation in the reflectance of the
substrate (paper) is the noise floor. Since the paper is not perfectly
white, there is a limit to how delicate the highlights can be before they
are more delicate than the variations of the paper itself. Therefore the
choice of paper may have a large effect on the dynamic range of the
printing system.
