I have a variant array defined as follows:-

var
  aTest : array of Variant;
begin
    setlength(aTest, 1);
    aTest[0]:=False;

    TLabel1.Visible:=not aTest[0];  // Compiles OK

    if not aTest[0]. then   // Compiler says "Expected boolean or integer but instead found not aTest[0]
       TLabel1.Visible:=False;
end;

Is this expected behaviour and if yes, why?

No, it's a "limitation" in the compiler.  It's not quite a bug because variants were originally only added to support JSON persistence and not actually documented, but they've been expanded over time to be used by everyone so I will make sure that this is fixed.

Thanks. I've worked around it for now by using:

if aTest[0]=False then   
  TLabel1.Visible:=False;
