No similarity whatsoever. A flourescent light heats its filament only during startup; in operation, it is a gas discarge tube. A CRT filament burns contin- uously, but at a lower temperature than the flourescent uses during startup. But your comment is correct: the stress on the filament of the CRT is not as significant a factor as others, e.g., surge voltages to MOS components. I do not ever recall seeing a terminal that had failed because of a burned out CRT filament.
