First of all, thank you for the great app I use Heresphere on my Quest Pro everyday and very happy with it!
Is there any chance for Heresphere app to adapt this kind of new features available on Quest Pro?
If this is just turning on some kind of switch then it would be so nice to have it. Pure black, better contrast like OLED!
You should notice improved contrast and deeper black levels in all your games. But you'll need run the command every time you reboot your headset, as forcing local dimming doesn't persist between restarts.
