I think you have to learn, pointing out that some design decisions are from your manager is a worthless point, I also have a coworker who doesn't have an opinion and changes idea on each contrasting message on a PR discussion, but you need to have yours and your knowledge and ability to reply, they hired you to contribute not to do what you are told, otherwise go be a policeman.
In the end someone told you to do something, and you didn't have the knowledge to disprove and YOU did that, not your manager
On the other hand they hired someone fresh of university who still need to create meaningful knowledge, so maybe they could've defined better the figure they needed beforehand
On the other hand, I think you should be happy and motivated to learn and improve for yourself, in few years probably you won't even remember your boss and managers names, and on the other hand I don't see any personal criticism in here, given the fact those are criticism and I see myself making too, and of course seeing an improvement or will to learn would definitely be seen as a good thing
