I'm familiar with the formulation of that material. It contains Optical Brighteners. Basically, it is modified with a material that will reflect light that is not normally in the visible spectrum. This makes the white brighter without decreasing the hiding. I tested a bit a few years ago (before it was commercialized) on my bathroom ceiling. It STILL looks really good... and... BRIGHT!
