ComplexIEEEFP not supported for Tiff objects?

According to the Mathworks website, the new Tiff class supports ComplexIEEEFP values for the 'SampleFormat' tag. However, when I tried to do the following:

%t is a Tiff class object
t.setTag('SampleFormat', Tiff.SampleFormat.ComplexIEEEFP)

I got an error message: Error using tifflib Void, ComplexInt, and ComplexIEEEFP SampleFormats are not supported.

Does it have to do with the fact that MATLAB only supports LibTIFF version 4.0.0? Or did I make a mistake somewhere in my code? I'm using MATLAB 2013a.
