This is true most of the time, but assuming your boss and coworkers are doing their jobs well (which is why it's not true most of the time) people will regularly communicate the things that are helping or hindering in their work.
Of course, you might find that your perfectly clean code isn't as helpful as you expected, depending on what you see as "clean." You'll learn that people care about how quickly they can understand and use your code, and whether they can make changes without worrying about breaking things. That's all they care about, and that's what "clean" is supposed to serve and accomplish.
