True Black Mode missing on tvOS

Hi on my 2nd gen ATV4K - setting option for True Black Mode is missing

Though at other apartment 3rd gen still have that option.

Everything updated to the latest firmware/infuse.

Can you check to ensure your Apple TV is in dark mode? Either manually or because of the Auto setting in Apple TV Settings > General?

Oh, it was in automatic. Turned dark and it’s available. So this setting only affects menu, and not playback of black content?

Correct. It changes the theme from dark to black while browsing in Infuse.
