object oriented – Presentation or Formatting logic?

If, let’s say, i have raw data in my database, and i am going to change the way it is represented while it is being displayed. Can i call what i am doing as my presentation logic, or it should just be called as formatting?

struct Card {
    var lastDigits: String

func cardLastDigitsFormatted(_ cardLastDigits: String) -> String {
    return "**** (cardLastDigits)"
