Linux can not control the brightness on the OLED panel in the traditional way [1].
Although there's a workaround from the community [2] that to execute script while brightness hotkey event is triggered. But if we want to upstream it, it's still a problem to recognize the OLED panel so that the system knows when to go workaround.

there's a kernel patch related OLED for reference:
