Strange white spot on my MacBook Pro 2017 screen

Hello folks, I bought the new MacBook Pro 13' 2017 in September last year and I always take a lot of care with it. I have protective covers, microfiber cloths (no chemicals, just with water) to wipe the screen and anti dust film to the keyboard during typing. However, since the end of January I discovered some dead pixels in some places on the screen, but what really worried me was a strange white spot on the screen. I tried to clean the screen, but the white spot is still there! Different from the dead pixels that I can only see them closely and on a white background, this white spot is easily visible in places with ambient light, especially when the light is illuminating the screen directly. I'm worried that spot and dead pixels getting worse and I'm also worried if the genius bar technician will say that this problem was caused by "misuse"', because I have great care with my Mac. I use it for my programming studies and related works on my Computer Science major, So I need this computer very much!
