Asus ProArt P16 laptop display supports 100% DCI-P3 color space, according to the specs.
I wonder if your laptop defaults to DCI-P3 color profile? This can be an explanation for your observation that "this OLED screen has a mild green/yellow tint."
DCI-P3 uses a greenish white point (CCT 6300 K, that might be more suitable for video) compared to the D65 white point, which is typical for photography. Also, DCI-P3 typically uses a gamma of 2.6, different from 2.2 in sRGB or Display P3.
If you have not already done this (I wish you provided details of your calibration), then re-calibrate the display. Make sure you use its full native color gamut (do not restrict this to e.g. sRGB in calibration), set the white point to D65 and gamma to 2.2.

I do appreciate your push for me to "not give up" on the calibration. So I had another go at it, and this time, I paid more attention to the details as per your notes.
Here are my starting conditions:
- In the Asus laptop, the color profiles can be controlled via the ProArt Creator Hub or MyAsus app - they are the exact same controls.
- There's 4 Color Gamuts (profiles) I can choose from, of which I'm using the default "Native" (Default Vivid colors)
- The others are: sRGB | DCP-P3 | Display P3
- Within the profile, there is a "Gamma and Color temperature" slider I can tweak. This is also in the default *Normal* state.
- I've turned off all artificial lights, and relying only on natural window light (it's a cloudy overcast day)
Then I ran the Calibrite PROFILER procedure, this time I'm choosing the "Advanced" workflow. Previously I ran "Basic". For reference, here's a manufacturer's video:
- ?t=353" target="_blank" rel="nofollow">Calibrite PROFILER Monitor Module Advanced
Here's all the settings I'm using:
- Screen type = OLED
- White point = CIE D65
- Target Luminance = 120
- Gamma = 2.2
Before the run, it also wants me to adjust Brightness, RGB channels, and Contrast to match a certain target.
- I only have brightness controls on the laptop screen, but not RGB or Contrast.
What was *very interesting*, is that it took a reading of the laptop screen's RGB values (before the run):
- This confirms that the screen is a bit green-biased (or rather, slightly below-spec on Blue and Red), but I can't change this.
Anyways, I ran the calibration, and the result was.... a profile which gave an even more sickly greenish tint. I quickly switched back to the factory default profile.
- On your comment about "did you limit the gamut in the resulting display profile in some way, e.g. to sRGB"... I'm not even sure how I would go about doing this, so I don't think this is happening.
So anyways... no joy once again.
...
For a comparison (and to allow a comprehensive assessment of my environment), I also ran the calibrator on my LCD, which is a VP3268-4K:
- https://www.viewsonic.com/global/products/lcd/VP3268-4K
- Billed as a "100% sRGB professional monitor"
I had full hardware controls on this monitor, including RGB. On the RGB-readings on the monitor before the run, it looked like this:
- So this confirms that all these years I've been editing with a very heavy blue bias...
- This explains why the laptop screen looks so... un-blue (to me) by comparison.
Anyways, after the .icc profile obtained from the calibration run on the LCD, I'm not sure I'm a fan of it either. It does look better than the resultant profile on the laptop however.
- I'll make a decision on this later. But at the very least, I've now manually dialed back on the Blue channel on the LCD, to what I think looks good.
Mind you, every uncalibrated screen I (or most others) use also has a blue bias. So if I now start changing my editing workflow with a profile from the calibrator, the colors are going to deviate pretty substantially from my previous work, and this is not an obvious good change.
Make of this what you will.
