Would this be necessary if I get my monitor colour calibrated using Calibrite's Display Plus device?

No, but a color profile only works in color management aware applications. It's not forced globally for absolutely everything like a driver-level clamp.

That leaves me to wonder how I should set my monitor settings (before colour calibration).

What's your settings as of today?

OK, are you suggesting if I use a colour calibration tool, to use it with monitor in "Wide Gamut" along with novideo_srgb "Use ICC profile" so that it persists in all applications? (See example of using rtings icc profile in above screenshot)

that's what I use. I noticed using EDID values for clamping made certain shades of blue look purple-ish. Rtings ICC profile had more accurate blue colours. I also use 10 bit dithering.

You colour calibrate your monitor using a tool and used icc profile with novideo_srgb?

Also, why use 10-bit dithering?

I don't calibrate, but that's the settings I use to clamp to sRGB.

And I use 10 bit dithering because it slightly improves colour banding compared to not using it. 6 bit helps the most but also adds noise at low refresh rates so makes the image look worse in general

Anyone else has a problem with image retention? Sometimes I get image retention, or is it a form of burn in?, but it's very strange, because the elements that stay on the screen are images that only were on screen for a (very) short time, like the ASUS start up logo, or the QR code on the Gaming tab in the OSD of the monitor (while elements that are on screen for a much longer time, like gaming UI's don't have retention...)... So I would be surprised if it really is burn in...

Friend has the same monitor and he has the exact same issue from time to time.
A pixel cleaning sometimes helps, but sometimes it doesn't.

We have a suspicion it's a bug when turning on the monitor (and in which order you turn on the monitor: before or after booting the computer), but we're not sure...

Had an LG CX OLED for four years now, and never had a problem like this...

There is a gray oval shape in certain near black scenes in the center of the screen. Is that normal or something I can disable? There is also a annoying grayish outline around bright lights in near black (like stars in Elite Dangerous) so that might be related.

I don't know if this is the same thing you're describing, but on my end I can see something like that when viewing SDR content in HDR mode, which means Windows 10/11 messes up the gamma and dark colors look completely wrong.

Sorry for late reply. reddit/r/OLED/comments/ga9rd1/lg_c9_weird_oval_at_different_levels_of_gray/ I am talking about something like this.

Yes this is a weird problem with this monitor. Boot-up menu (which is probably impossible to burn-in) image retents or you see Windows Clock in grey scenes. It sometimes fixes it by just restarting. I found that starting the monitor with lower brightness helps with this.
