[Nexus 6P General] Metallice:
I think the simplest answer is that the 6P is using the same technology and process and the Galaxy S6 - and not the Note 5. This would explain why people have the said the Note 5 display looks *slightly* better than the 6P, but the differences are minor. Whatever minor improvements Samsung made to the manufacturing process between the S6 and Note5 are missing in the 6P. If it was the Note 4 panel you'd think the differences would be greater and more apparent, unless Google and Huawei did an *amazing* job at calibrating them. Also, considering that phones are designed and built well in advance, it would make sense that the S6 panel process would be the "latest generation" at the time Huawei/Google placed the panel orders.

The size difference between the S6 and 6P panels isn't an issue, as Samsung has shown that they can be flexible with resolution/size using the S-series panel tech/process. For example, Moto's Samsung AMOLED panels or the Nexus 6 which uses the S4 panel tech/process at both a different resolution and size.

Also the brightness difference just boils down to stock Android not having the ability to overdrive the panel. Without the overdrive, my S6 edge gets just about as bright as my 350 nit computer monitor, but in direct sunlight when the overdrive boost kicks in it gets almost twice as bright at the cost of supersaturation, horrible gamma, weird contrast, etc.

It's not like it's new for Google to leave out useful software features in their Nexus devices that seem obvious to everyone else... e.g. double tap to wake on a device with a rear fingerprint sensor (but Nexus 9 has it for some reason?) or a working LED that isn't used for notifications but instead is only used for indicating a severely drained battery.

(Sorry for the rather long post/essay. Got carried away. I see this misinformation spread so often... and Samsung and so many news outlets have contradicted it so often that I had to say something)

Anyway... Samsung absolutely would. Samsung Mobile (phone maker), Samsung Foundry and/or Semiconductors (semiconductor manufacturer for Exynos), and Samsung Display (AMOLED manufacturer) are all semi-autonomous companies under the Samsung Group umbrella (although tecnically Samsung Mobile and Samsung Display are daughter companies of Samsung Electronics which is a daughter company to Samsung Group). Similar to Alphabet being comprised of Google, Calico, etc. Samsung is comprised of almost 100 seperate companies - health care, oil and energy, engineering, research, health insurance, and Amusement parks/Resorts. They stay seperate out of necessity. Why should Samsung health insurance be managed and run by the same people who run Samsung oil and energy?

Samsung Mobile gets no special privileges when it comes to purchasing parts from their sister companies. They've said it numerous times. The reason Samsung used Snapdragons up until the 810 fiasco was that it was just simply better CPU/GPU/Radio performance for the price compared to the exynos socs, again, because Samsung Mobile get no special privileges buying Exynos SOCs.

The semiconductor department isn't going to sacrifice their own profits selling their chips at cost just to make Samsung Mobile look good. Having to use both Exynos and Snaprdragons for different regions most like comes down to supply needs considering how many phones Samsung has to build/ship/sell in a certain time frame.

As for Samsung Display, they have said openly that they are trying to sell their latest smartphone displays, but "nobody" is buying. I don't know why, but it might come down to the price or the lack of solid relationships between the Samsung Display and other phone manufacturers. Samsung Mobile can probably afford the AMOLEDs, probably has a good relationship, and at this point it's a big differentiator for their phones. Otherwise, you mostly see Samsung AMOLEDs in Chinese manufacturer phones. Maybe they are the only ones with a strong relationship with Samsung Display.

As for Moto and their use of old Samsung panel tech, maybe it comes down to price, as Moto has been shooting for low price flagships for a while now, or maybe Motorola spends much longer designing and building their phones so by the time they come to market theppanels are very old news.

On that note, LG and HTC have both said that Nexus devices are an insanely rapid 6-month start-to-finish whirlwind. That rapid pace might explain how Huawei was able to secure very new Samsung panels since they started shopping for parts rather recently.

(With those 6 month quotes, my guess would therefore be that the 6P has a S6 generation panel (at best) as opposed to a Note 5 panel)
