Read dng image using the Tiff class and the display image is black

Hello,

I am trying to read a raw image into Matlab. I have used the following code:

warning off MATLAB:tifflib:TIFFReadDirectory:libraryWarning
t = Tiff('test.dng','r');
offsets = getTag(t,'SubIFD');
setSubDirectory(t,offsets(1));
cfa = read(t);
close(t);
imtool(cfa)

When I ran the code, I got multiple warnings such as bellow:

Warning: TIFF library warning - 'TIFFReadDirectory:  Unknown field with tag
33421 (0x828d) encountered.' 
Warning: TIFF library warning - 'TIFFReadDirectory:  Unknown field with tag
33422 (0x828e) encountered.'

I checked my Adobe DNG converter settings and I have used the following settings:

Any clue?!
