=== Assistant: Good thinking. ===
Good thinking. A screen recording is actually the right artifact to check here — and there is useful metadata, but also an important limitation to be aware of.

I’ll keep this precise and technical.

==== ### ====

From a screen recording file (on iOS), metadata can show:
* Orientation changes (timestamps when rotation occurred)
* Frame size / resolution
* Color space (sRGB / Display P3)
* Bit depth
* HDR / tone-mapping flags
* Frame timing irregularities
* Dropped or duplicated frames

This can confirm:
* when the display pipeline was reset (rotation)
* whether color processing mode changed
* whether the GPU output itself was stable

===== A screen recording cannot capture: =====
* post-render display controller artifacts
* local tone-mapping bubbles
* panel-side inversion effects

Because:

: 

So the absence of the dots in the video is expected — and actually supports the diagnosis we’re on.

==== Here’s what would be meaningful to look for: ====

===== If the recording metadata shows: =====
* a clean orientation change at the exact moment you rotated the phone
* followed by normal frame timing

That confirms:
* the pipeline reset happened cleanly
* the artifact disappearance lines up with orientation rebuild

===== If the metadata shows: =====
* consistent color space (e.g., Display P3)
* no HDR toggling
* no dynamic color profile switching

That rules out:
* software color filters
* accessibility color transforms
* app-level rendering issues

===== If there are: =====
* no massive frame drops
* no corruption
* no repeated frames during the artifact appearance

That tells us:
* the GPU output was stable
* the issue is downstream (display controller / panel driving)

==== On iPhone: ====
# Open Photos
# Open the screen recording
# Swipe up on the video (ℹ️ Info panel)

Look for:
* Resolution
* Color profile
* Frame rate
* Orientation info

If you AirDrop the video to a Mac, you can also:
* right-click → Get Info
* or open in QuickTime → Inspector

You’re mainly checking that nothing unusual changes except orientation.

==== Red flags would be: ====
* dots appearing inside the recording
* artifacts encoded into frames
* metadata showing frequent color-space flips
* recording showing partial inversion regions

You’ve already implied that none of that is happening.

==== If: ====
* screenshots are clean
* screen recordings are clean
* artifacts reset on rotation
* artifacts drift back in afterward

Then the only remaining layer is:

: 

There is literally no other place in the rendering pipeline where this behavior can occur.

==== Just answer yes/no if you want: ====
* Does the recording show any visual anomaly at all?
* Do the artifacts reappear after a few minutes of normal use?

If you want, you can also paste:
* resolution
* color profile
* frame rate from the video info panel, and I’ll sanity-check it — but don’t expect “hidden clues.” The absence of anomalies is the clue.

You did the right diagnostic step.
