I did some more searching and wanted to share my findings with everyone.
According to Aston Martin literature, Morning Frost White is a "
striking tri-coat white with a hints of blue pearl". It has been displayed at many motor shows, such as L.A., Geneva, and Paris.
After searching the AMOC forum, I discovered this picture, which clearly shows the difference between Morning Frost White (left) and plain metallic white (right). Morning Frost White is a striking tri-coat color with blue pearl specks.
Based on this, and everyone's responses, I am confident that the original pictures I posted are Morning Frost White. I have posted them again, for reference, along with a picture of Jchoice's Morning Frost White vantage coupe.
