Equivalent of AGDCDiagnose with apple silicon macs?

[toke lahti]

In the past info about video connection to a display told about bit depth and chroma subsampling in System Information.
Not any more.

How to get that info?

Anybody?
Please help!

I need to verify is my mac driving my tv in RGB or YCbCr.
The tv (UE49KU6645) does not tell that.

I don't have Sonoma to test, this works from Terminal in Sequoia to get the Depth

defaults read /Library/Preferences/com.apple.windowserver.displays.plist

You could also use BetterDisplay https://github.com/waydabber/BetterDisplay or a similar app to get the info.
