My experience of the TabVisible property in Delphi and Lazarus Win32 is
that TabVisible makes the tab label where you click visible, ie the
contents of the tab can be visible (using the Visible property) but the
caption for the tab can be hidden and that is what the TabVisible property
is there for. My experience also indicates the same.

snippet from Delphi 7 help
===================

Description

Use TabVisible to temporarily remove a tab sheet from a page control. When
TabVisible is false, the tab does not appear in the page control and its
TabIndex property is -1. *Setting TabVisible to true allows the user to see
the tab of the tab sheet again.*
