may I know your viewing environment is dark room or bright room at night. what value  setting of oled light  are you using ?

bright living room on day time
the preset are good enough for now.
not yet explore much on oled setting. probably one day will try

my sofa is 3.3m  away from TV,  55" inch is too small. I have to wait 65 inch to  drop price .

Spent the last several days , testing my C8 . This bad boy is kicking some serious asses .
I must say I particularly love the new BFI on C8 ,  I can sit closer to the TV without getting dazzled by all the hardcore action scenes now .
Also for gamers , the new dynamic tone mapping makes a Day and night difference for gaming  . Wouldn't recommend it for movies though  , especially those mastered in Dolby vision are already very bright .
Last year they patched the OLED with a nerf on the brightness and APL , causing the a lot of games , such as Horizon Zero to look way too dark. You can offset this by turning on dynamic  contrast, however this cause a lot of details to be lost behind the brighter area.  The dynamic tone mapping is different , they analyze metadata and selectively brighten zone or object carefully with the new a9 CPU , the result is HDR highlight and zones that look a lot more iluminating than any OLED TV, yet retaining most of the fine and delicate details on screen .
I know a lot of reviewers say it isn't worth the upgrade from last year , but that is because they are not primarily gamers . For me , this feature alone is good enough of a reason to upgrade from last year's model.
My verdict : if you are a gamer , the C8 along with other 8 series  ( except B8  ) are probably the most amazing TV money can buy now  . The AF8 seem to still struggle with input lag , and Sony's OLED approach to the HDR just doesn't seem right to me , they choose to go for the brighter route and overblown the HDR details ,  one of purposes of getting a good HDR display was to check out all the glorious details behind the bright and colorful lights to begin with .

For SDR , in a darkroom you want to keep the OLED lights lower so the brightness look more comfortable (100 ~ 200 cd/m2) and natural to the eyes .

The settings suggested by rting is not very practical because they calibrate their TVs in a completely sealed , dark room without any source of lights .  I find 62 on ISF Dark room with contrast @ 85 ( ~ 200 cd/m2  )  to be perfectly acceptable assuming you have a wee bit of light from kitchen , street lamp from the window etc .

Don't mess with the Dolby Vision OLED lights setting above 50 as it changes the gamma .
LG do minor calibration for their TVs before shipping out . That's why everytime after I replaced the default OLED screens  , the settings feel a bit off and had to be calibrated again.

While this is by no means  , comparable to hiring an experienced calibrator , the out of box settings should be accurate enough for most people .
The last few % is to make your chart look prettier and the color temperature closer to 6500k , average Joes won't notice much of a difference .
If you are one of those AV enthusiast aiming to get closer to perfection , there's when you hire a calibrator . Post calibration I noticed better near black details , colors look a little more natural especially skin tones of human look extremely realistic .
