Remarks

This checks only if the category is set visible or invisible individually. Other Revit mechanisms may also affect the visibility of elements of this category, including:

• The category classes settings for model categories, annotation categories, import categories or analytical model categories.
• View filters.
• Elements hidden individually in the view.

Thus the return value may not reflect the actual visibility of elements of this category in the view.
