There should be a reference to the 'Available' property
The Visible property is closely related to the Available property.

Getting the Visible property gives you the actual state of the object, i.e. if you can see it on the screen, it returns Visible = true , and getting the Available property is more what we would expect from the previous behaviour, which is roughly the answer to the question: 'will it become visible if I click on its parent'
History
After setting, Visible state cannot be read back immediately

Note that if you set item.Visible, you will not be able to see the change in your debugger, or read it back from your code immediately.

i.e. The first example below will exhibit unexpected behaviour, while the second one works:

item.Visible = DecideIfItemIsVisible();
if (item.Visible)
  ...



bool isVisible = DecideIfItemIsVisible();
item.Visible = isVisible;
if (isVisible)
  ...
