AW2723DF, HDR on and probably similiar monitors with "HDR washed-out colors problem"

I am the owner of the AW2723DF monitor (with latest firmware M3B104) and I am writing in connection with a rather well-known problem. Where when HDR mode is on, the colors in the unlit areas of the monitor are “washed-out” because some auto-brightness or auto-dim function is running, I don't know what to call it correctly. It looks terrible and I guess every owner of this monitor knows it. HDR despite the rather high luminescence on this monitor is unacceptable. BUT, there is one free game on the Steam platform (PinballFX) where turning on HDR mode somehow “spoils” this monitor function responsible for dimming the screen (most likely it's local dimming) and after turning off this game, any game I turn on later in HDR mode has great light and great colors, at the expense of slightly brighter blacks. This GREAT effect persists until I turn off the monitor completely, when I turn the monitor back on everything goes back to normal and HDR mode looks terrible again (washed out colors, auto-dimming, etc.). I believe that if we, as users, had the option to disable local-dimming in the monitor, you, as the manufacturer, would make us, the owners of this monitor model, completely happy. Is there such a possibility?
