That doesn't change that the two suppliers may have different production methods. This is no different than the samsung vs TSMC, both delivered the A9, but using different manufaturing process.
No, you are comparing Apples with Oranges. This is nothing like the Samsung and TSMC A9 debacle. CPU manufacturing is entirely different than display manufacturing.
Please stop posting non-sense without providing factual based sources for your claims...

Not all pixel are created equal. If it is two different suppliers, the pixel may not behave 100% identical. Sharpness is defined by a lot more than just resolution.
Your source compares two
entire different display technologies. PLS and
IPS are
not the same. PLS is a different display technology to IPS, like OLED is a different display technology to IPS. The displays manufactured for the iPhone are all
IPS panels.
If Apple gives guidelines to the manufacturers for creating S-IPS panels, the manufacturers create S-IPS panels and not PLS, OLED or VA panels. The manufacturing process for displays stays exactly the same for every display, the pixel-grid is assembled the same way etc. If Apple wanted H-IPS panels, all manufactured displays would be H-IPS panels. There would not be some S-IPS panels, some H-IPS panels and some e-IPS panels and so forth.
Your saying that it is the same like the Samsung vs TSMC, 16nm vs 14nm A9 debacle, but than provide sources for entire different display technologies which can't be transferred to your analogy. Your point with "not all pixels are created equal" applies to entire different screen technologies, but not to within a manufacturing process of a certain technology.
With your analogy, comparison and your provided sources you basically imply that Apple - to use your falsely used comparison - did put an A9 chip in some iPhone 7s and an A10 in other iPhone 7s...
What I think you want to try to say is that while all displays are manufactured with the same technology, there are still differences. That is true, even if displays are created on the same manufacturing line, they still are not exactly the same.
But the important thing to take notice of here, is that after calibrating the iPhone displays, especially the new ones with the new P3 color spectrum, the differences between those displays in terms of color, brightness etc. is
not noticeable without proper instruments to measure them.
But to come to my original point for posting in this thread. I'm not saying that there are no problems with the screens of the 7. There is the issue with the claimed "25% more brightness" and questionable things like the sapphire glass on the camera lens/home button etc.
My point was that with the new P3 color gamut the displays of the 7 look in general warmer and have a more accurate white point and more accurate colors than the cooler displays from the 6s and 6 series. And some people seem to do the mistake of associating a warmer screen = bad and a cooler screen = good.
