I updated my post with links to better videos that I recorded. The recordings are done with a 1st gen iphone SE not the 2020 version. All the tests were done with ditherig running on an intel g4560 using the IGP so the flickering shouldn't be from the OS.
The lagom and blurbuster pixel inversion tests do show pixel inversion issues at certain settings on my monitor. But at the setting that I recorded the updated videos at, I could not see any pixel inversion with the naked eye.
Here's a microscope video I recorded of two patterns at one monitor setting that showed visible pixel inversion and one setting that didn't.
I don't know what to make of it. I don't really see much difference between the visible and non visible tests. The subpixel flickering in all the videos seems to be occurring at 30hz, half of the 60hz display frequency of the monitor and the phones. The iphone SE first gen did not show any pixel inversion issues to the naked eye when using both the blurbusters and lagom test.
I paid about $20 for the microscope on amazon.
edit: It actually seems that there is indeed very minor pixel inversion issues with the p24h-10 monitor. They were only visible when I went full screen and carefully cycled through each pixel inversion setting. It wasn't visible when only viewing the initial image with all 12 examples shown at once. It seems to cycle around 2a, 2b, 4b and 7a when changing monitor settings. The 7a being subtle enough that is only visible when viewed full screen. I tried full screen with the iphone SE 1st gen and wasn't able to see anything with the naked eye.
edit 2: Interestingly the pixel walk goes away at maximum setting, which are the setting that I recorded the original microscope dithering videos. the screen is too bright at max setting but I guess I'll just try compensating by wearing my maui jim sunglasses since they also help increase the contrast and reduce ips glow.
