AW3225QF, Dolby Vision is not being properly activated

I am running the latest Nvidia Driver and the latest AW3225QF M2B105 firmware from the 25th of April.

Every time I boot the PC, Dolby Vision is not being properly activated. Although the AW3225QF shows the Dolby Vision as activated, all colors are being showed completely off and opaque. But turning OFF and ON Dolby Vision fixes the issue bringing all colors and brightness back to normal. This happens with all DB modes. When booting the PC up and checking at the Dell Display Manager APP, it shows Dolby Vision ON, but also Smart HDR toggle ON which is a very odd behaviour. When switching Dolby Vision Off and On this also solves the issue. Note that this issue was evident even before I installed the Dell Display Manager.

This behaviour also happens when the display goes on standby after certain period to refresh pixels. This should get fixed as it is absolutely annoying and should not allowed for a £1k top brand monitor.
