Vivoactive 3 homescreen and some other screens dim

I dropped my watch in the toilet. Right after the homescreen became very dimmed. And weird thing is after I change the watch face it became okay. 

I know I can just simply switch watchface to solve the issue but this is my favourite watchface. Menu on longpress is also dimmed on the top part. Refer images

I have done factory reset and refer images for reference

Watchface name - Coros Vertix2 like
