Can I exchange my MacBook Air with green or blue lights on screen with 15 days of purchase?

screen has marks， and it shows green or blue light when I look at it. I find it very uncomfortable to see. Today happens to be the 14th day since I bought my MacBook, and I was wondering if an exchange service would be available. I need to use it every day, and I would feel uncomfortable if I have to return it and buy a new one. However, I am worried that the Apple technicians might think this doesnot affect the usage and refuse to offer an exchange or return. Although I have an appointment for an inspection this afternoon, I wanted to confirm in advance.
