Lots of CFRP bikes are clearcoated, not painted. Besides, we are
discussing potential longevity, and any paint or coating can
deteriorate in less than the time span in question. That a coat of
paint can forestall UV damage for a few years does not make the issue
disappear-- if UV can damage CFRP, then that would put some limit on
how long a CFRP bike can last, at least if it's ridden outdoors by
daylight.
