All modern plastic bumpers painted the same color of the car are off to a degree. You car is not unique and if you have a discerning eye you will always see it and not unsee it. In fact once your tuned to seeing it you see it even on high end luxury vehicles. Most people will either ignore or miss unless your OCD then it will bug you to no end.

This is also not just bumpers but factory side skirts as well. What makes matters worse is the unibodies are quite often sprayed on the assembly line separate from the factory side skirts and bumpers i.e . All plastic or polyurethane trim. . This can lead to a even wider color discrepancy due to paint being done in batches.
Ford actually even has a warranty disclaimer about this so you cannot claim warranty paint work on it. In other words they know full well about it and say oh well.
Sorry if this comes off flip but I have an eye for detail lean towards the OCD side of things and actually went through it on my car. I can’t help but laugh about the futility of It now.
Of course on the other side I actually did have paint warranty work done for a basically bad bumper spray job where the paint did not even make to the inner edges of the intercooler opening of my 18. I had other friends check their cars and some had this issue others did not. In other words the spray work at the factory was kinda sucky. But hell we bought a high performance economy car.
