The values that you are reading of the calibration tile are absolute
values. Thus from your example you can see that the tile is relatively
flat, but it less than "pure" white in both luminance and color. The
calibration process of the spectrophotometer does not change the values
of the tile (or make it 100% white!) but verifies that the instrument
still reads it properly. A white tile or opal is used because it is
*relatively* flat across the visible spectrum, and thus all wavelengths
can be verified.
