Volkswizard had a Mk7 R in Lapiz Blue (2014 I think?) and had some problems with it - check out his channel. Some of the problems related to the paintwork around the front of the car. From his latest video, I don't think he necessarily dislikes LB as a colour, more that it reminds him of his previous car and the problems he had with it. If you discount LB, you have black or white and black is possibly the worst colour for showing up scratches and marks.
