How to check if a parameter value is read only? (not the parameter itself)

There is a shared parameter, which is filled with Dynamo. In some elements, these values are calculated automatically within the family and are read-only. The task is to filter out such elements or families.

Please help!

Parameter.IsReadOnly should report this correctly:

In this example one of them assigned in the family (true) the other one is added only in the project
