True. You can always learn more. Even after you break through many ceilings, you will keep finding more things that you don't know. Also, the incentive to improve gets smaller as you get better - Doesn't matter how many ceilings you already broke through, the incentives for continuing will always go down because beyond a certain point, there are no financial or even career benefits to getting better. It's possible for a developer to be skilled beyond a level which their bosses, recruiters and colleagues are able to grasp. You're not going to get paid extra for that surplus skill. Your pay is limited by your boss' imagination. Even though those skills are extremely useful and deliver real returns. Proving yourself as a developer to a non-technical person takes years because that's how long it takes to see the results. In a big company it may even be impossible to prove yourself because your work is mixed in with that of many other people and the results average out.
