I have this problem with Origins and sometimes Odyssey too, but no other HDR game that I've ever tried. Enabling HDR simply makes the black levels in-game grey and elevated, washes out interiors, and visibly changes the color palette of the game making everything a bit more brown, more so in Odyssey when it comes to color.

Every cave or pyramid in Origins looks like a mess with HDR on, and turning it off goes off great blacks and contrast like it should be. In Valhalla this doesn't happen, in Odyssey it happens sometimes, but always in Origins. I tried every combination of Nvidia control panel settings and nothing works, I think it worked one time by using RGB limited color space, but that's not working now either.

It has nothing to do with the TV and its HDR settings as 10 or so other games I have with HDR all look great and proper with it enabled, but Origins messes up black levels completely and looks terrible. Did anyone have a similar problem with it?
