As expected, there must be more to the story here than “Samsung good LG bad.” In prior years, which serial prefix had the best performance of each generation has not been consistent. Some years it was theorized that the Samsung panels had fewer issues, but in other years the Samsung panels very clearly had uniformity issues.Did further tests. iPhone 17 Air LG Screen vs. iPhone Pro Max 14 Samsung.
Front: Both are very similar. Overall, the LG Screen is calibrated towards more warm.
However, off axis there is a notable shift towards red on the LG Screen unfortunately.

In Dark Mode, the LG Screen looks better - has better black levels and overall more crisp display.
Personally i prefer the Samsung Screen due to the whites are not so warm.
It is no doubt also a matter what you prefer. Both are great screens in their own field.
Overall the Air is a fantastic device and I would immediately switch if it would have the same screen quality like my iPhone 14 Pro Max. I maybe will keep my 14 Pro Max until I see an Air with a Samsung Screen.
I am typing this from an Air with a GVC panel, and it looks nothing like your LG panel off-axis. No obvious warm or green coloration off-axis in any direction. Very clean looking display.
I think it’s more of an individual panel lottery than anything.
