I dont think so, Plus they are even more easily scratched, This is purely a quality issue, This issue is there in Coure aswell, You can notice the same on Corolla door handles/Sidemirrors. (i think its due to low quality of plastic) as the issue is less in Corolla bumpers.
But even then Corolla bumbers are also not painted in the finest manner. Suzuki and Honda have better finished (painted) plastics.
