Screen glows a green color after being exposed to humid room

I purchased a refurbished LG Velvet which after receiving it I realized that the screen has been replaced with a cheaper one than the factory version. I brought it into the bathroom to listen to my podcast while showering. Unfortunately the humidity must have affected the phone and gotten inside. After several days in rice I attempted to turn it on. Near the navigation panel the screen began to almost glow a green color which then spread to the remaining areas. That was months ago. Is it even fixable?
