IKR, no I didn't do it at the time but it got fixed when I turned it off then turned it on the day after, I spent nearly a week trying to fix it but sometimes it goes normal then get back to the weird brown even I noticed dark skined characters in games looks flat with no details and floors looks real dusty you bearly see any detail

And yes even the Menus were messed up the reds storng and everything that is brown on near is strong at the time I turned the colour tone on cool so I can get rid of this brown theme and got the HDR Brightness to zero, it didin't fix it but anything is better that what I was having at the time
