New paint adapts??

Hello together, I have a small big problem. And that’s when a nice person scratched the boot cover of my 206 CC. The car is Chronos Silver metallic, color code EZR. Now I was extra in the Peugeot workshop because I assumed that I would get a best repair of the damage there. I was told it didn’t have to be painted the complete lid, but you painted it, so only the horizontal area where the Peugeot lion is located and you would not see any color difference. For 170 € I let that happen and the result is not so good now. If the sun doesn’t seem to be directly on it you can see nothing, but in the bright sun the newly painted area sparkles much more than the other “old” paint. Znd if you look sideways on it you can see that the area looks like a slightly brighter cloud. Now I was in the works to address that and there was told me that the new paint will take about 4 weeks. Can it really be that? Can’t I just think about it’s going to change it?
