I don't know what kind of nostalgic glasses people wear, but CRT TV quality degraded over time, became noticeably blurry. Had Panasonics, Sony, JVC, all looked like shit. Monitors with degaussing were fixable for a short time.
Most modern enthusiasts replace dried-up capacitors and retune the bias/constrast and focus voltages, which brings them back to stock condition as long as the tube isn't too heavily worn (a rejuve will sometimes fix that as well)
