Thanks, it's from this very old project of mine, and it's relevant to the current discussion because it's 2x2 scaling of the original icon (four pixels have replaced each single pixel in the original):

What you seem to forget is that Apple was out of the display game for a good long while and that it was rather surprising to many observers that they re-entered it in the first place. So my guess is that Apple will do neither a 32“ nor a 40“ 8K display as both of these things are way too niche for modern Apple. Even the existing Studio Display and Pro Display are more „fan service“ than serious business cases for Apple and we can count ourselves lucky if they‘re updated every few years.
Edit: also, do not underestimate how stubborn Apple can be once a line has been drawn (hello, one button mouse). If 220 PPI has been defined as „perfect“ (as in: all the human eye can discern) for the typical desktop viewing distance, by that same definition everything above that is „overkill“. The only way for an 8K display from Apple to ever exist that I can see would be if at some point in the future they wanted to update the 32“ Pro Display and 8K displays were so common by then that they can‘t even source a 6K panel anymore. But that scenario seems very „far out“ to me, in more ways than one.
You make good points, but here’s my take:
[1] Apple stopped producing external displays from 2016 to 2019. I know what you mean, but Apple was hardly “out of the display game” — LG Display produced four Apple-only variants of the iMac 5K panel assembly between 2017 and 2020, not to mention the displays in their core products: laptops, tablets, and phones. Displays are absolutely, inescapably integral to Apple’s business. The bleeding-edge technologies in the ongoing Vision Pro experiment underlines this reality.
[2] There are signs that the lesson from 2016-2019 is the opposite of what you’re suggesting. Research and development for the Pro Display XDR was underway by 2018, the same time the A12Z was in development — the foundation of Apple silicon in Macs. The Studio Display uses two new, Apple-only variants of the iMac 5K panel from LG Display, one of which is an entirely new part number (LM270QQ29) for the Nano-texture glass. Apple single-handedly created the 32" 6K category and moved the needle with regard to matte glass.
[3] Let’s go off the deep end for a moment and talk about model identifiers. In 2021 Apple completely revamped their system, a reform that includes AppleDisplay2,1 for the 2022 Studio Display (J327). The 2019 Pro Display XDR thus seems to be (retroactively) AppleDisplay1,1 (J290, the original identifier “iSim1,1” was deliberately opaque). The forthcoming 2026 Studio Display (J427) will almost certainly be AppleDisplay3,1.
The use of "Apple Display" is suggestive. Think of "LG Display" and "Samsung Display" -- Apple could be tired of its dependence on third-party research and development, and I could see an initiative similar to the Apple Silicon move, though perhaps not quite so all-in.
[4] Regardless, odds are you are correct about the next-generation Pro Display (J390?), a 32" 16:9 6K with 4,608 (256x144) miniLEDs would be the sweet spot in 2026. But 8K 120Hz would be next. The broad range of uses for 8K resolution in the visual arts and motion environment is niche only in the sense that the creators who can really use it are small in number, but the audience for that content is large, wide, and compelling. There is a lot of money on the table.
