I know it's possible to compress a RGB image using JPEG compression and YCrCb colorspace using COMPRESSION_JPEG & PHOTOMETRIC_YCBCR.

Is it possible to compress a CMYK image in a TIFF using JPEG compression and YCCK colorspace?

The recently published Adobe Photoshop TIFF Technote indicates that the photometric must matched the jpeg compressed data so YCCK can't be used.
