I think the good CRT life cited was because they were good CRTs, period. The instant-on probably shortened the life, not lengthened it, but even then they were still good. Hot/cold cycling doesn't reduce cathode life as far as I know; I think it would only help reduce filament failure due to mechanical stress, which I believe was an almost non-existent problem to begin with. Every opinion I ever heard in the labs at Motorola and Zenith was that instant-on shortened CRT life.
