God of War is really annoying with HDR on.
So the HUD off suggestion works wonders, but having no information on your health status or the enemy health status and such is a pain too.
It seems the TV detects static bright images and then proceeds to dim the entire screen.
In god of war combat outside in the bright world, it makes it seems like night has started falling suddenly, but it is the TV dimming.
I have no issues in HDR tv shows or movies, because these do not have static elements in netflix or blu-rays.
Adjusting the Peak luminance setting to medium makes the dimming less noticable, because the image has less dimming to do.
Having it on low made me not notice the dimming at all, in fact this seems like this is the setting the screen dims too when it does dim.
Peak luminance setting on high is the standard setting for HDR though and you want the peak brightness high for HDR highlights, so setting it to low makes you miss some of the beauty that HDR offers.
I have not checked raising the peak luminance on SDR yet and do things like watching sports, the feeling i have now is that those that have this problem with SDR, might have their peak luminance setting on high for SDR or something? I have it off normally in SDR, so in SDR i never noticed a problem.
So for those that don't have this problem, playing God of War with HDR on and HUD on, makes the peak luminance setting go from High to Low every damn minute until you head into a menu or something and the screen slowly brightens to high peak luminance again.
This dimming is pretty actually slow when it activates, so you are sometimes fooled into not noticing the change happening immediately, but then you suddenly think at times, why is the image so dark?
I will try to find some God of War spoiler free bright areas where i can show the dimming on youtube, or perhaps just demo it with the menu screens.
This will probably not show up on camera as clearly as you see it in person however.
I wish i could roll back the firmware, the difference dolby vision makes is not worth HDR game issues.
This TV was expensive, to think a sony firmware update made this product worse for me without an option to make it better is kind of hard to swallow.
