PUBG looks weirdly saturated with my Kingbank Silver DDR5 6000 and certain filters. How do I fix the distortion?

I first tried cranking Digital Vibrance in the NVIDIA Control Panel, but the game looked like a cheap oil painting with nasty white halos around objects. Following visual report NO.KBD-VIS-07, I switched to GamePP's AI Enhancement mode. I dialed the sharpness down from 60% to a range of 35% - 42% and killed the auto-saturation. HWiNFO showed VRAM usage hovering between 6.2GB - 6.8GB, easing the render pipeline. Now, distant grass isn't just a green blob, and I can spot enemies at 200m clearly. Still, in heavy rain, I see some slight color blocking—likely a limitation of the AI algorithm handling extreme dynamic lighting—but it's a million times more natural than before.
