It’s not trivial. An LED only needs power to light up, an OLED Pixel always needs the GPU to be powered on and it would be a significant power loss to implement a pixel sadly
The full Always On Display (which shows the clock + some notifications) uses less than 1% battery per hour on my ancient S7, are new phones not any better than that?
None of this is true. It may happen in practice on some poorly-designed devices, but the “GPU” in the SoC can remain powered off, and the display controller remain in low-power mode.

I mean there’s a ton of phones that have always on displays (AOD)
