Hi William,
DaVinci Resolve 18.1.3 and macOS Ventura 13.6.4 are very old versions. Using exactly the same versions and older version of the MC plugin our QA department was able to reproduce this error at our side too. The MC plugin itself supports BT.709 and BT.806, so there is no limitation that would lead to this error. The Resolve Studio has a huge list of gamma tags and each has own purpose. In case a tag does not match the names we use inside the MC plugin, we set it to default settings. Looks like that was the case in the combination of the old version of macOS, Resolve Studio and MC plugin. The new version of the MC plugin correctly sets bt709, as in your settings, and this does not cause any errors or problems.
Therefore, we suggest you to update DaVinci Resolve to version 19 at least, also to update the MC plugin to the latest 1.7.1. Please carefully read the Release Notes, there is a conflict between different NVIDIA SDK versions used by MC plugin and RS, so maybe you want to stick to the previous release 1.6 / 1.6.1.
Please give it a try and let me know how it goes.
