This is a 3-levels tiff with the original AdobeRGB gradient, the
sRGB/Relative and the sRGB/Perceptual ones:

The provided tiff is non very interchangeable. You write to a audience which is not completely photoshopaware. And the content of this tiff file is unfortunedly not visible in a specification conformant way beside the first tiff directory.
Despite Adobe maintaining the Tiff specification, they regulary emit files containing propriarity data. What bothers me is they "lead" the industry by omiting possibilities, which are defined in the Tiff specification. E.g. I see here only a 8-bit dithered green gradient starting from the half of the picture in AdobeRGB. The tiffinfo command gives not much more information other that a big data blob hidden inside the file.
As a recommendation, you might send next time a better defined tiff, a series of baseline tiffs or PNG files. The later format can be checked with almost any web browser. Thanks for considering. 

kind regards
