What you are talking about is not code that is written at a "master" level, what you are talking about is code that is clever. An important part of mastery is understanding what kind of code to write, when. Mastery means writing code that is easy for others to read and modify, when writing code in a professional setting. Mastery can also be writing clever code with "aesthetic beauty", in a different setting like an academic or personal project. But people who write clever inaccessible code while working professionally with a team have a few more steps to walk toward mastery.
