Apple tv 4k - colour calibration

I just purchased an Apple TV 4K as an upgrade to my old TV HD. It works but the colours are bleak in comparison to my okd Apple TV. I tried the calibration with my Iphone 11, with the latest IOS installed. The process starts but a quarter through the process a get an error message. Is it my Iphone or TV or HDMI cable? Please advise and note I have an older TV with HDMI 1.2 I believe.
