rendering issue

I'm experiencing a very strange rendering issue in Battlefield 6 that only affects multiplayer in SDR. The single-player campaign looks completely normal with correct exposure, natural colors, proper highlight detail, and balanced shadows, but multiplayer is heavily overexposed. Bright areas become completely blown out, white surfaces lose all detail, sunlight is extremely intense, and the image looks like the tone mapping or exposure is broken. This is not a simple brightness issue because lowering brightness, gamma, or contrast only makes the whole image darker while the blown highlights remain clipped. Interestingly, enabling HDR makes multiplayer look much closer to normal, but I don't want to use HDR because I prefer the more natural color reproduction of SDR on my monitor. I've already compared and edited the multiplayer and single-player config files, reset all graphics settings, cleared DirectX and NVIDIA shader caches, regenerated configuration files, reinstalled the NVIDIA driver, tested different graphics settings, and verified that there are no unusual NVIDIA App overrides. None of these steps changed the issue. The campaign and multiplayer appear to use different rendering pipelines, because the exact same PC, monitor, and GPU render the campaign perfectly while multiplayer consistently has broken SDR tone mapping. My system is an RTX 5060 8GB with Game Ready Driver 610.62 and an AOC Q27G4X monitor. Has anyone experienced this issue or found a fix?
