In the system information, under “Graphics / Display”, the software of the studio display can be seen, indicating that it runs “version 15.4 (build 19E241).” This is the same build number as iOS 15.4 and iPadOS 15.4, indicating that the studio display runs the full version of iOS.
The studio display features the A13 bionic chip, the same chip as the iPhone 11 lineup, the 2020 iPhone SE, the ninth-generation iPad, with its 12-megapixel ultra-wide front-facing camera with center stage, and audio to support a six-speaker sound system. The presence of the A13 chip suggests that the display may run some form of existing Apple software, just as the HomePod and HomePod run the version of the Mini TVOS, so the exact software of the device is still unknown.
Yesterday, when the first reviews of Studio Display were released, there was a general complaint among critics that the image quality of the built-in webcam is anywhere in their hands test, from “old BlackBerry” to even “terrible”. In his detailed review of the studio display, Gruber said the camera is “disappointing” and “surprisingly bad”, the image is “terrible” and the center stage is “shiny”.
