Cold War 120FPS HDR Not working

Recently Cold War has started not to display in hdr while in 120fps mode, whenever I start the game up it’ll show a quick black screen and then the tv will show it’s no longer in hdr mode but whenever I switch to resolution mode (60fps) and start up Cold War it shows it’s in hdr, my tv supports hdmi 2.1 120fps hdr so I don’t know why it’s doing this because it’s worked with 120fps hdr on Cold War since launch
