Automation: How to tell if the host is in Read or Write mode

I wonder if there is a way to find out in a plugin if the host is Read or Write (Latch) mode.

Especially for Read mode I would like to "fix" the automated sliders - now I can move them but they of course jump back to the Read level, which looks odd. So I am looking for a better UX for this, add some indicator to the automated controls and prevent this jumpy behaviour.

Thanks in advance!
