The iOS 17.1 update that Apple is set to release in the near future addresses an issue that "may cause display image persistence," according to Apple's feature notes for the software.
Since the launch of the iPhone 15 models, there have been sporadic reports of severe screen burn-in impacting the new devices. There was speculation that it might be a hardware issue with the OLED display, but based on the iOS 17.1 update, Apple has found and addressed a software problem that mimicked screen burn-in.

While most of the reports of display problems were coming from iPhone 15 users, there were also some users with iPhone 13 Pro and iPhone 12 Pro devices that saw similar issues, which is likely why Apple's release notes do not mention the iPhone 15 specifically.
Those who have noticed "burn-in" on their iPhones should update to iOS 17.1 to ensure that it solves the problem.
The iOS 17.1 update also addresses a number of other bugs. It fixes an issue that could cause the Significant Location privacy setting to reset when transferring or pairing an Apple Watch for the first time, plus it addresses a bug that could cause custom and purchased ringtones not to appear as options for a text tone.
There is a fix for an issue that could cause the iPhone keyboard to be less responsive, and Apple says that it has added crash detection optimizations for the iPhone 14 and iPhone 15 models to further refine how the iPhones respond when a vehicle crash event is detected.

Apple's iPhone development roadmap runs several years into the future and the company is continually working with suppliers on several successive iPhone models at the same time, which is why we often get rumored features months ahead of launch. The iPhone 18 series is no different, and we already have a good idea of what to expect for the iPhone 18 Pro and iPhone 18 Pro Max.

Weird, I was assured by so many on these forums that this was an existential problem for Apple that would prompt a massive global recall and be the end of the company.
you can't fix "burn in" with a software update lmao. it's obviously an issue with the graphics processor (if it's really been fixed).
It could very well be a software bug that is not related to the graphics processor. Modern OLED displays utilize software algorithms to mitigate screen burn by essentially keeping track of how long individual sub-pixels are lit, and at what intensity. This allows them to adjust nearby pixel luminance to account for the degradation that the pixels have encountered from normal use, and continue to produce a clean image on a display that would otherwise have screen burn. My guess is that there was a bug in the display driver firmware that caused these algorithms to overcompensate for the amount of usage that these screens were seeing, essentially causing it to over adjust the luminance of certain pixels resulting in what looked like real screen burn when these compensation values were utilized by the display driver.
