Are anyone else's 996 screens also yellowed-looking and dimmer? I look at photos and videos of other 996s, and they seem to have a brighter screen, no color shifting outside of just how the light refracts on the lens. But on my 996, the colors are slightly yellowed and dim. I don't remember if it looked that way when I first got it or around this year. It's almost 2 years old, why is it like this? And what can I do about it?
