Fenix 6X Sapphire - Backlight always slightly on

I just got my Fenix 6X Sapphire yesterday, and my problem is that the backlight is never 100% turned off, so when in a very dark room, e.g. bedroom at night time the watch is "glowing". 

I have tried to reset it, I have the settings to only activate the backlight when pressing buttons. 

Anyone having any ideas about how to solve it? It sounds pretty much like the problem described here: https://www.reddit.com/r/GarminFenix/comments/bhmu8v/fenix_5x_backlight_always_slightly_on/

I have attached a photo in a very dark room where the "glow" can be seen.
