Suzuki swift silver colour 2025 model , colour fading away

Good day

I'm reaching out for help regarding my 2025 Suzuki Swift in silver color, which I purchased in late March 2025. However, since May, I've noticed the silver paint on the front and rear bumpers fading, with the rear being more pronounced.

I contacted the dealership in Gauteng where I bought the car and sent them pictures, but they attributed the issue to the bumper being plastic and the body being metal, claiming it's normal for them to have different appearances.

Given that the car is still under warranty and I've only had it for less than 3 months, I'm concerned about the long-term durability of the paint. Has anyone else experienced similar issues with their Suzuki Swift? I've attached pictures below for reference.
