Coming from an LG Oled CX, the contrast and 3D feeling are inferior, as is the response in games. If your usage is mostly gaming, then Oled is the only way to go.
Now, moving on to the C8K: very good packaging, amazing build quality with an aluminum frame and sturdy base which has 2 height positions, remote control with aluminum appearance and night lighting (finally).
Google TV menu is very fast, no lag even after heavy use, the built-in player plays everything so far, all HDMI ports are 144Hz, the first one is eARC.
The panel is not matte but semi-glossy, so it loses in some areas and gains in others. It's not like the Samsung QDoleds that turn purple when light hits them, it's not like the LG Woleds that are like a mirror, and it's not matte like the S95F which raises the blacks, it's somewhere in between, but with such brightness, it doesn't matter much.
The default profile is Standard with eco settings on, so I set it to Movie, and Filmmaker is good, it has motion smoothness off so there is stutter, Movie is set to Low and I prefer it.
Personally, after some research, I set the profile to SDR MOVIE and changed the following: BRIGHTNESS 50, Dynamic contrast off, Peak Luminance Off, all Clarity OFF, Motion Smoothness Low, and of course Dynamic BRIGHTNESS OFF.
If it seems dark to you, just change Peak Luminance from off to Standard, and if you want more, then High.
In HDR I set Movie and only changed Clarity all Off as well as Dynamic Contrast off.
In Dolby Vision I have Dolby Vision IQ and changed Motion Smoothness to Low, also always all Clarity off.
The picture is wonderful, the brightness is unreal, and only the S95 and G5 can compete with it in HDR Impact from Oled.
Motion at 24 frames is fine, not like the Sony Xh95 I had, but quite good.
The upscale in poor quality movies is also good, again not like the Sony Xh95 but at LG CX levels.
Viewing angles, even though they say the new panel has improvement, the truth is there is very little difference, it's at the level of Samsung Qled, so if you plan to watch from an angle, forget it, get Oled.
When you sit straight, there is no blooming at all, in general there are moments that remind you of Oled.
As for whether Mini LED technology is more durable than Oled... time will tell.
At this price and if you sit straight, it's a good choice if you watch in a very bright living room (that was the reason I chose it). And since the higher S95f and G5 are much more expensive... I had no other choice.
