I've found a minor bug respecting this feature. Since the brightness now is managed per display, the default color correction options are being saved with the old method, per screen ( like 0/RedBrightness=-0.600000 ), and this settings are ignored, so the default color correction saved in '~/.nvidia-settings-rc' isn't working.
