Leaked code references upcoming Studio Display & possible other new monitors
The next-generation Studio Display may arrive soon, and leaked code shows that it at least exists internally after three years without updates to the original.

Apple's Studio Display is due for an upgrade
Apple hasn't forgotten about the Studio Display, though it has been slow to announce a new model. The expensive 27-inch Retina Display with 60Hz refresh and LED backlighting isn't super appealing when the market is flooded with ultra-cheap OLED models.
According to leaked code discovered by MacRumors, Apple's next-generation Studio Display is alive and well with codename J427. However, there's no hint as to what features it may have or when it will release.
A second reference, J527, was also discovered, but it is unknown which device it could be referring to. It could be a different version of the Studio Display, a new Pro Display XDR, or a different device altogether.
Apple's display proved somewhat controversial when it launched since it was backlit by LED and lacked faster refresh rates. While it was Retina 5K, consumers were quick to point out that similarly specced models were available at nearly half the price.
That, and Apple seemingly never took real advantage of the A13 processor beyond normal monitor processor functions.
The next Studio Display has been rumored to be quite the upgrade, though some of it may be wishcasting. Jumping to mini-LED backlighting and ProMotion could prove cost-prohibitive.
Apple could announce the updated Studio Display at any time. If it is imminent, it could launch either in the fall along with new M5 Macs or in the spring with updated MacBook Pros.

I’ve always preferred to pay for quality, rather than for something that’s trying to be quality, using cheaper components that just aren’t up to it over the useful life of the product.
I wouldn’t go near an Asus monitor. They have long term problems I’m not willing to deal with.
When the brightness is higher, the uniform backlight raises the brightness of the black areas, reducing contrast. Mini-LED and OLED dim the black areas of the image.
Mini-LED with ProMotion at the same price point would be a nice upgrade.
For enthusiasts, graphics professionals, and text heavy users, miniLED or OLED would be worth it. Not so sure about the mass market. Even your picture here is pretty subtle for the mass market of users to notice. In normal room lighting, I think most people wouldn't notice the difference. Like, I've put the iPad Air 13" and the iPad Pro 13" side by side at the Apple store, and you have study it.
It's really only in dark rooms where the black blacks would actually be noticed. Nice for me as I use my iPad in the dark all the time, but most people?
Oh for sure, we use Apple displays for HDR jobs, but for all other work we have Asus. Would love to have mini-led and ProMotion, but I'm afraid it will not come at a good price. We'll have to wait for competition. The 32" Asus is great for coding though.
What I'd like is maybe a not quite so premium 30" display. A 32" would be better but would cut into XDR sales. There are TV monitors that can do ok for casual viewing. To that point I'd be happy with a 30" version of my iMac's 5K display even without a mini-LED or OLED panel.
It sucks that I can't use it as an external display without a hack that's beyond my skillset. Even then it would still be only 27". So I guess I'm wishing for (certainly not ever expecting) a display worthy of a 30" 5K iMac.
