When you change the numeric format of PropertyGridItem using Format function, the change is not immediately applied to the number (type Double). If you edit the value or set the value after code, then the format is applied. Should be applied when Format string changes too.

To duplicate in VB6, place PropertyGrid on Form1 and add the Form_Load code.

Private Sub Form_Load()
    Dim pi As Double
    pi = Atn(1) * 4

    Dim fmt As String
    fmt = "%0.9f"

    Dim pgiCat As PropertyGridItem
    Set pgiCat = PropertyGrid1.AddCategory("Category")
    pgiCat.Expanded = True

    Dim pgiChild As PropertyGridItem
    Set pgiChild = pgiCat.AddChildItem(PropertyItemDouble, "Child", pi)
    pgiChild.Format = fmt 'this doesn't display right away

    Dim pgiNext As PropertyGridItem
    Set pgiNext = pgiCat.AddChildItem(PropertyItemDouble, "Next", Null)
    pgiNext.Value = pi
    pgiNext.Format = fmt 'this doesn't display right either

    Dim pgiSibling As PropertyGridItem
    Set pgiSibling = pgiCat.AddChildItem(PropertyItemDouble, "Sibling", 0)
    pgiSibling.Format = fmt
    pgiSibling.Value = pi       'this displays correctly.
End Sub
