I got a launch day base 17 with a GVC and unbearable green shift even at the slightest angle. Switched to the pro got a G9P which had almost no shift and was significantly more vibrant with much better blacks. Decided to play the lottery once more and got a pro with a G9N which has more shift than the G9P, however it is cooler and a bit more vibrant (better color depth without the excess warmth of the G9P). Torn on which to keep, leaning towards the G9N due to the more vibrant on axis view.

The debate of G9N/P appears to come down to personal preference with the N running cooler. Both are excellent panels overall but still a step down from my previous launch day 13PM with an immaculate G9N.
Kinda funny that you describe much better blacks. Since black means the pixels that display black are actually off since it’s an OLED screen.

The day had to come, when even Samsung’s turned-off pixels are better than LG’s panels lol.
Obviously the absence of light is the same on both. Do you guys not understand that contrast is effected greatly by the anti reflective coatings that have variance between manufacturers. Or do none of you recall the chatter with Samsung putting matte antireflective coatings on their qd-oleds? (Less perceived contrast vs standard glossy panels).

Samsung and LG use the glass and antireflective coatings from different manufacturers for iPhone screenproduction, mainly Corning in the USA. Remember: Apple designs the phone, so LG and Samsung produce the screens based on Apple’s demands and use Apple’s specifications.
 
I've have two of the 17 Pro Max. One with G9N, the other GH3. The G9N is unquestionably brighter (by multiple shades), crisper, with deeper/richer colors. The two screens are remarkably dissimilar. No excuse for having the exact same phones with such extreme visual dissimilarity.

The GH3 is going back. No guilt here... Where's the quality control?
This was exactly my experience. My first 17 Pro Max looked dull and lifeless from the get go compared to my 16 Pro Max. Then, I read this post and ran the diagnostic and found that the panel was a GH3, so I got another 17PM to try, and after setup, before checking the panel, I noticed that the screen looked much brighter, and the colors were richer and more vibrant. I ran the diagnostic, and it’s a G9N panel. Both panels had color shift at angles, but looking at the screen normally, the G9N is much more pleasing to my eye.

I know it’s subjective, and others have a very different experience, or will prioritize their screen in a different way. Your mileage will vary. For those that like the LG panel, I’m happy for you: no criticism from me. I’m really delighted with this G9N for my usage.
 
This weekend I swapped my G9N 15 Pro for my partner’s GVC Air. I’d been using the 15 Pro for over a year, and while I could tell the difference when working alongside my LCD MacBook Air, it wasn’t dramatic enough to feel like a major change. However, after spending two full days using the GVC Air, going back to the MacBook now feels almost painful, MacBook screen seems dull and lifeless by comparison. That’s how sharp, vivid, and downright satisfying the GVC Air is.

There is no such thing as a debate between the G9N and P. What you are experiencing is the normal difference between OLED panels. Two G9N would look slightly different as well, it’s total nonsense to base this on the OLED panel number.
This! I got a 17PM with a G9P and a regular Pro with a G9N. They both have slight variations between each other and actually my G9P looks slightly cooler and less reddish (especially at min brightness). These are just regular panel variations, there’s no panel patten there between the serial numbers.
 
Would you return? I checked and it’s a G9N

Saw two GVC air side by side, one GVC was noticebly sharper and better calibrated than the other.

On the better unit, pixels and rendering looked more defined, almost like looking at a real photo through glass. There is big variations within the same manufacture and even serial number. I can only speculate some oled panel's subpixels are not aligned properly in the pentile matrix grid.

I don’t know what PM to keep. I have a G9N and GVC screen.

GVC screen typical green shift when tilting towards you. Head on it’s perfect.
Samsung screen no color shift but not 100% uniform. Upper half is tiny bit warmer than bottom half. So on light backgrounds and scrolling it’s noticable. Only on true tone on. When it’s off and my screen is cooler there is hardly any difference. Debated to just not use TT but I kinda like it.

So basicly green shift vs not uniform.
I'd go with LG anytime (uniformity is a must for me).

The underlying OLED pixel structure is not a black hole. Even when off, it reflects an appreciable amount of light. The amount can certainly vary across different panel manufacturers.

G9Q here in the Air.
Like most others in this thread, you forgot to mention colour, storage capacity, and continent of purchase.

Without these details we can’t notice any patterns. If I was Apple, I wouldn’t be allocating panels randomly. I’d put better ones in phones more likely to be bought by discerning customers. That appears to be the case with the regular and Pro phones, with the Pro getting more Samsungs. But is it also true with black versus gold Airs, or 256 GB versus 512 GB? We can only find out if commenters give the relevant bits of info. It’s not hard.
