This is only my conjecture and impossible to prove, but I suspect that Sarnof, when he asked Armstrong to develop noise free radio reception, wanted noise free *AM* radios that could receive existing RCA NBC owned AM stations. Armstrong delivered FM, which was low noise but (and this was likely a BIG BUT) required new broadcast stations and transmitters and a new band. Which would take time and be expensive. Would also require trying to sell FM radios in markets with only a few stations. Also (and this is probably the really big issue) FM would distract and suck off consumers away from Sarnoff's next big thing: Television. Maybe if Armstrong had suggested using FM sound for the soundtrack for television images to Sarnoff, Sarnoff might have seen this combo as a "killer application" product. A one-two punch. "Great sound and you also get to watch the action too".... Then the Armstrong Sarnoff pjssing contest might not have happened....
As for the shadowmask color CRT, Heard that Philco was trying to develop a color CRT based on other methods. "Apple" code name, saw it somewheres on the web. There's the stripes of colored phosper on the screen and a single electron beam idea, the beam switched RGBRGB in time step as it sweeps
across the phosper stripes. Issues on keeping track of which colored stripe the beam is now hitting area major problem for this scheme. Especially when the image has large black areas, you lose track. Would have gotten rid of convergence problems though. But so did the color wheel, but that had motion artifacts and wasn't compatable with B&W NTSC.
