Photoshop doesn't support ITULAB.

Photoshop only supports CIELAB and ICCLAB encodings in TIFF.

One of the reasons I hadn't tried adding ITULAB support to my color conversion tool (Argyll/cctiff - see http://www.argyllcms.com/doc/cctiff.html) is the lack of suitable sample files, whereas it was possible to check my LAB TIFF files against Photoshop.

I wasn't attempting JPEG in TIFF Lab though.
