My two pence worth, firstly I'll come to Renault's defence (can't believe I'm saying that). Not only is LY a metallic colour it's also what's called a 2 stage pearl. The short of this mean that when the paint is applied direction of spray has a massive impact so the way the light hits the metallic particles changes based on direction. If you remove a panel from one area of most LY cars and put it against a panel on the opposite side of the car chances are it will look different. The thing that's important is the panels that are adjacent match each other.
However, the colour of the part of the left doesnt look correct to me, like it's missing a stage or that it was just done badly. For me it lacks the metallic sparkle that you get from LY and the greenish effect. I've had parts of our LY 182 resprayed, to get it done and matched in well was both time consuming and expensive, a body shop really need to know what they are doing to match LY and I'm not sure the people that sprayed that do.
