As Joris pointed out, you actually get Y Cb and Cr planes. So the first component, that looks red, is infact Y, and indeed has the correct size. But the Cb and Cr planes are downsampled. At least this is what I got here.

What if the file is jpeg-compressed cmyk? The TIFFTAG_PHOTOMETRIC tag says it's cmyk, not YCbCr. I expect cmyk data in this case, but it sure doesn't look correct.
