in ff7 rebirth you literally cannot remove the eye adaptation/auto exposure, i set all the main options to zero and nothing happened
r.XeSS.AutoExposure=0
r.DefaultFeature.AutoExposure=0
r.EyeAdaptation.LensAttenuation=0
r.EyeAdaptationQuality=0
r.EyeAdaptation.Focus=0.000000
r.EyeAdaptation.MethodOveride=0
also setting the volumetric fog to 0 (r.VolumetricFog=0) strangely cases a heavy white haze in closed environments, specially visible in under junon
some settings are baked into each other so removing them causes unexpected results, it's not as simple as you claim
