Thank you for your hard work!
It was disappointing to learn that the screen supplier model is no longer available for view in the app now.
However on the positive side we indeed saw a pattern here with those variable refresh rate panels. Its crazy that they can go as low as 30fps and suddenly spike up to 120fps. This will naturally cause screen tearing and eye discomfort because the visual before you is not stable.
I'm not sure if those engineers in charge even took/ underwent any basic Human factors 101 courses. This basic knowledge of inconsistent visuals motions and how it affects us cognitive is like one of my earliest chapter for introduction to human factors engineering. It also elaborates on how its affects our perception of our surrounding ~ thus contributing to increased stress levels to maintain our perception of stability~ so just to operate the device.
Anyway, naturally the best workaround to this awful problem is to forcily control the FPS through v-sync but this again creates even far more discomfort to some users.
Bravo I say! Imagine them introducing a problem of variable refresh that we didn't ask for, then introduce another "workaround fix" that also introduce more problem. This is really spiralling downwards to a rabbit hole.
Thanks for sharing on the different panels as well! It's really absurded that the panels can vary so much like in Day and night.
Before I even went to your comment to see which was the more comfortable screen for you, I immediately noticed a strong discomfort coming from the right device panel.
It's like the device's screen has been applied with an additional blue layer of filter on top of it, and use some kind of brightness and contrast enhancement to make the text unnaturally pop.
I did tried to replicate this effect on my macbook pro m1 late 2020 model.
I went into color filter settings and applied a cyan color overlay. Then I go the option below it and boost the contrast level from 100% to 110%. Lastly, I went to my color profile and changed it to P3.
Indeed, I feel rather sick just by looking at my screen. Thus I do think there is some software at work as well for the panel's display driver.
On this topic, I was wondering for a while now on why some IPS lcd seem to be presented so differently. Now disclaimer I have been a big fan of IPS LCD since it first arrived to the market. Thus I am fully aware of the pros and cons IPS LCD panels as well. Recently, I have been coming across this term called "IPS LTPS LCD" and how it differs from IPS LCD. Strangely, I found that I often have discomfort with only with LTPS LCD screens.
Referring to the above, one can see all 3 devices are set to very high brightness. Among the 3, LTPS appeared to look the best since it was able to retain its contrast despite the high brightness, while boosting shadow highlights higher and reducing overexposure lower (just compare the water fountain of the LPTS vs the other 2 panels ).
Now this is extremely unnatural again. From my experience with IPS LCD, this is its typical behaviour. If you set IPS LCD above its recommended threshold, color will begin to look overexposed with a white overlay.
The few panels that seems to be able to retain shadow highlights and overexposure at higher brightness are oled panel and mini-led panels. Strangely, LPTS LCD are also able to do this. Coincidently, looking at LTPS LCD for me gave me some form of discomfort (not factoring in PWM, or other flickering etc. )
I think LTPS LCD is some kind of a hyprid panel between OLED and IPS displays to cut production cost of higher end panels while retaining some of the benefits of OLED or Mini-LED.
Strangely, the iphone 7 plus uses Retina display - IPS lcd which I never had any problem but the iphone 11 which uses Liquid Retina display which (I believe some models) uses LTPS Lcd gave me the same level of discomfort.

Based on the above article, IGZO panels and LTPS LCD panels are similar in characters. Coincidently as well, I never found any IGZO panels comfortable to look at for prolonged period. They tend to look very unnaturally contrasty. Thus I have stayed away from using most Japanese exclusive made higher end LCDs panels since then.
Ironically, as TFT panels starts to phrase out, IPS LCDs panels are becoming the new lower end panels of display.
Pfft. Are we the new peasants now? Probably we are!
Since we are in envy of others that they can use (mostly) any panels without any immediate symptoms in return. We are also going around "scavenging" for lcd panel in the non-premium section, just so that we can satisfy our basic needs of not getting any symptoms. 🤣 🤣
