My X also came with 3M protective tape (just on the front portion of the bumper) however after some 6 years it was clearly showing the effects of time plus the ends & edges weren't as tidy as they were originally. I decided to take mine off and when I did I could clearly see it had done it's job. I don't believe removing it will damage the paint, it didn't on mine.
If I were you I'd get a professional to remove and replace it with Xpel 3M Clear Bra:

Front end protection was also discussed on this recent thread:
