As AOSP is becoming even more closed source (only QPR0 and QPR2 will be released normally from now on) and you may be curious about GOS lore (because it's going to be the only timely patched form of Android), here's a snippet of it.
I'm sure sharing it to ask questions is a quick way to get banned in GOS communities btw.

When I noticed significant fringing on an S20+, I thought it's a phone specific skill issue, because the supply chains are longer and responsibility gets diffused. Turns out that a 2025 OLED monitor is the same. It's quite plausible that the controller does support the needed corrections for subpixel rendering (SPR), and yet a monitor company failed the only job they had.

Here's the S20+. It's not a limitation of the subpixel array. In case of one, the colors would be switching sequentially like on a thin cable shot far away with a Bayer sensor. Here, the individual colors are evidently "centered" with a bias to the expected center of the pixel. This allows them to reliably drift in their own direction.

And pretty much yes, I believe that some of the people who thought PWM irritates them, may actually dislike misconfigured subpixel rendering. While fringing is one thing, some of the SPR configurations can result in blur. It's a fairly straightforward topic that probably isn't going away just yet.

BTW, think of it as a litmus test for every "reputable" """keybox extractor""" wannabe (I'm speaking of all keybox sellers who claim to extract them from devices rather than OEM leaks) who won't manage to do anything despite the writeup. Since it couldn't…
To be clear, Keymint remote key provisioning changes this to a really massive degree.

https://android.googleapis.com/attestation/status

This json will either disappear at some point, get redefined or grow to megabytes, since device-wide (all units running the same build during a given time frame) public listing of revocations would no longer be practical – the banned "serials" would supposedly have to be per each unique app installation. Yes, I'm still trying to comprehend it. No, collecting unit-unique public keys at the factory and uploading them to Google isn't the whole story.

Tldr: if whoever decides to play by Google's rules, attestation/PIA/screen proxying from a device you personally own may actually let you live in peace, but for all it's worth, it really seems that Google won't have to choose between revoking a whole device (bad for PIA adoption) and letting non-compliers in.

To benefit from the new level of control, Google will likely just break the promise of:
"Additionally, Google backend servers are segmented such that the server which verifies the device’s public key does not see the attached attestation keys. This means it is not possible for Google to correlate attestation keys back to a particular device that requested them."

If they won't, why all this effort?

As a matter of fact, I do wish someone would test this Google's promise, there's nothing to lose because the architecture for granular revocation is now in place and changing it would only be a change of policy, not of client side implementation.

I missed a very important event from years ago. Moto invented a charger that differs in its max power depending on how you put it in the socket.
