Clarification on page whiteness

[fantastic_four]

In an article in this month's Comic Book Marketplace, Steve Borock wrote the following:

 

Whenever there is a "split" page quality like "off-white to white" pages it means that the edges are the first color mentioned and the center is the second color mentioned. We feel that the split page quality is the best way for the buyer to visualize the page quality instead of giving it just one color/shade. CGC would be doing a disservice to the consumer if the edges of the pages were cream and the center was off-white by only calling the pages "cream" while at the same time giving pages that were cream all over the same designation.

Does CGC also use the "split" page quality descriptions to describe pages with a uniform color that falls between the major whiteness descriptions?

 

For example, Steve's explanation suggests that the "Off-white to white" description on a comic could mean that part of the interior is off-white and other parts are white. Could the description also mean that the pages are primarily one color that is the approximately midpoint between the "Off-white" and "White" page quality descriptions? Or is the description only used when the page quality is mixed?

The split page quality is used only when the page quality is mixed. "OFF-WHITE to WHITE" means that the edges are OFF-WHITE and the quality gradually changes to WHITE at the center. CREAM (or any other single designation) means that from the edges to the center the pages are CREAM, if there is a difference from the edges to the interior, it is too minor to differentiate.
