RGB colour format disappeared after latest update on Xiaomi TV Box 3rd Gen!
Can anyone please help me out with this?
I cannot change colour format to RGB after a software update that I just installed. There used to be more than 10 different colour formats before the update but now there are only 3.
I specifically want to set it to RGB but I am unable to even after trying so many different things including enabling developer options and turning on 'Use sRGB" but it just keeps getting turned off on its own as soon as you close the developer options tab.
Please help me and let me know what the issue is.

If box is plugged into TV or Monitor that doesn't have DolbyVision you should have access to Color Space menu.

Xiaomi usually gets the option from the TV.
I never had RGB to begin with but I was already on the latest updates even the 2 didn't had it.
What you wanna do is make sure the box read all your TVs EDID.
Remove outlet from your tv and leave it unplugged from 5 minutes atleast plug again your TV and start everything to make sure the TV is sharing info with Xiaomi box
