AW3423DWF Firmware M3B107, A07-00

Hi all,

Having some issues with the new firmware, M3B107, A07-00.

Gamma:
Is anyone else having washed-out gamma issues with this firmware?
Some HDR titles and even SDR seem a bit washed out.
In addition, my screen seems a bit yellow after updating the firmware.
I've had to create a custom color profile to try to offset this.

Functionality:
Lost access to brightness and contrast in Standard mode.
The other strange behavior I've noticed is that sometimes when I turn the monitor on and off, the internal fan ramps up at full RPM. Turning it off and on again fixes it.
I didn't have any of these issues on the previous firmware.
Are we able to revert to the previous version? If so, where can I download it?
