SdmIf you say its a bad update then you're mistaken. There were several major issues that were pending since a long time which now has been addressed to. I am sure that the RGB function in Camera app will be resumed if not it is resulting in some other problems because of it. So be patient and wait for a response from the Team.
Now it will automatically turn off rgb when you open camera app
At least they should add option to turn off or on this feature
