Now that's problem one and it creates issues with HGIG looking darker than it should.
Problem number two: Color Booster doesn't work in game optimizer mode.
Here is a photo of my qd-oled gaming monitor playing this video
Notice the colours, particularly how vibrant the red neon sign is:
Now here is the same in game optimizer on the G6. What happened to the vibrant colours? See how the red looks orange and all the colours are dull, even the greens and yellows. Its because the colour booster tech isn't working in game optimizer
How do we know the colour booster isnt working? Because here is what it looks like when I enable filmmaker mode.
And I've just spent an hour trying every setting under the sun to try and make game optimizer looks closer to the image of film maker mode and I just cannot, the colours always looks significantly worse in game optimizer
The combination of the HGIG edid issue and the issue with colour booster means that currently HDR gaming is pretty much completely broken on the LG G6.
Does the G5 have these issues too? I don't know, but if LG doesn't fix this, I would say gamers should look at Samsung TVs
I hope Vincent from HDTV Test can bring this up in his next video because he didnt test any of this in his review and its a massive problem
