It depends on the company and how they treat your job, but mostly as a worker you are there to fulfill a company's requirement. Unless there's a position or incentive to go that extra mile, don't, most companies will never see it. Even if you want to do the extra work for yourself, I'd recommend to find a way to do it as a hobby if it's unrewarded, separate from work.

What they will see is the absence in case they do need it, and then they will be required to fulfill it, although they may not want to focus on better and more empowered workers with higher expectations and may instead just focus on quantity over quality by hiring more people to fill it. Even worse, don't be the guy who makes his (and other's) jobs obsolete to scummy bosses.

Open your eyes, you aren't in school, you aren't getting rewarded for better grades at work unless they make it part of the business and your bosses stick to it and not just plugging in friends, buddies, and associates.
