Failing display?

I have a MacBook Pro, Late 2013. It's the base dedicated GPU config (2.3/16GB RAM/512SSD), and AppleCare until March 2017. My display is a Samsung, IIRC. Recently, I've noticed that the backlight has a green tint around the edges, and the whites, sometimes, a pinkish hue. Is my display starting to go? The green tint becomes far less pronounced if I leave it on a white background...

Thanks,
