> something to put on the CV for the next job.

spoiler alert: you can put anything in your CV without actually doing it. I've had the experience of dealing with people who I have high doubts did this. From the looks of it have been reward for it for more than a decade.

> the reward is the intrinsic satisfaction of a job well done,

just because it applies to you do not mean it a universal shared experience.

for some it's not even satisfaction that they get from that it a frustration and a feeling of being cu*ed where they put in the effort and someone else get the reward.
