I see. I think I may have misspoken on the relevance of the temporal dithering video specifically.
What I mean is that the static matrix photo needs to correctly represent the horizontal and vertical axes in order to characterize the panel accurately, and the disparity between it and the video indicates that one of the two must be wrong.
Most AMOLED phones have the dots running at 45 degrees to the display edges, which corresponds to an incomplete PenTile RG/BG matrix. This is what the video shows. But the static matrix photo shows them running at 90 degrees instead, which suggests that they may actually be arranged in a full-matrix pattern with four dots (RGGB) per pixel. If true, this would make for a higher-detail panel that doesn't exhibit a "de-resolution" effect in heavy red and blue shades. But if not, then the photo is misleading.
What you say about the slippery screen on the microscope makes sense. I'll concede that it probably doesn't matter in the video how the device is rotated, as long as we can trust the photo. The photo orientation really should be correct if at all reasonably possible.
