Colour GPU Preview and CPU Preview on M1 Macbook are still not correct

[ubishere]

The notes shown on the latest InDesign 18.2.1 update indicate that this version solves the colour discrepancy between using CPU and GPU Preview modes in Mac Ventura. Unfortunately, it has made no difference in my case. Colours still look much more saturated in CPU preview and overprint than GPU preview as before.
This happens both when attached to my external monitor and also when it is disconnected (restart after disconnect).
 
MacOS 13.0.1

M1 Max MacBook Pro 1TB 32GB Ram

I must admit I had not realised that Apple had updated Mac OS to ver 13.2.1 - since updating this has now fixed the colour discrepancy.
