Even with a "ghost emblem" it should start to fade out over time. You have paint that hasn't seen any light and some that has faded. The part that hasn't seen light will fade faster. Obviously if your paint has faded badly (you will know this when you take the emblem off) it will take much longer and may never go fully away. Most likely, you will see it fade in a year or so to the point you have to look for it if not up close.
