I’ve played with settings again but can’t get that same quality.
This sounds like the ABL(Automatic Brightness Limiter) is kicking in, and sadly this is nothing you can do about as it's a "non-user" setting.
On my Sony AF8 there is a setting for Peak luminance(high, medium, low of off) which does impact the light output greatly thus it doesn't
affect the ABL, but as you allow for higher peak brightness of the overall picture it at least widens the range the ABL works within.
I don't know if LG has something similar in their brightness settings?
With that said thou, I recall seeing a review from "HDTVTest"(pretty sure it was a LG C8 comparision) where they did a test with ABL disabled which could be turned off/on through the Service Menu.
However I'm positive that you would void your warranty, if any, by turning this off and last but not least, ABL is there for a reason.
it's controlling maximum power consumption as well a protecting your panel(subpixels) from producing to much light hence avoiding premature degradation and possibly other unwanted picture problems like permanent burn-in.
So I would strongly advice not
to fiddle with this even if you find a way to do it.
