Soon I'm going to connect Xiaomi devices to pretty old TVs.

Xiaomi Mi Box 3 to Pioneer PDP-434HDE. Box has 4:2:2, 4:4:4 and RGB modes. Pioneer TV has option to choose 4:2:2, 4:4:4 or RGB in its HDMI video settings.

Xiaomi TV Stick 4k to LG 22LS3590. Stick has Android TV 11 and I could find no color space settings, maybe they located somewhere else now? LG TV has no info or settings for supported modes.

Which color space mode should I choose?
