I think the 15GP22 is just going to be limited in performance due to two factors. First, the phosphor dot pattern is a bit large for the screen size, so it's going to give GE Portacolor levels of resolution. Second is the red phosphor which is going to limit overall brightness as well as needing to run the red gun much harder than the other two.

Something I noticed when I had my set running is what looks like a horizontal brush stroke pattern in the upper third of the faceplate. It appears like it's behind the flat faceplate surface. It becomes noticeable when there is a bright area of solid color, like a bright blue sky, for example.
