Redout too dark/wrong colors HDR on LG B7

[Topera Xerosa]

Hello guys, I don`t know what is wrong, but Redout is really too dark in my screen, when HDR is on I can`t even see the shapes at the menu background, and the color looks too saturated and really dark, does not matter the resolution I set. My screen is set to 3840 x 2160 and I'm using YCbCr422 8bpc Limited. Assassin's Odyssey runs really fine in HDR, but Redout won't. There is anything I can do?

On Win10 / Vega64 / Samsung C32HG70 it kinda works when I put it in borderless window, but some elements of the interface are totally white and intelligible, while some tracks look fantastic but other look like SDR video played on an HDR stream. It's very shoddy, I don't think it's supposed to work like that but I don't think I have any other PC HDR games to even check...

Same problem on a Samsung Q90R. HDR is enabled in WIndows and in-game. Nvida output is set to YCbCr422 12bit.
