Yes, but perhaps not in the way you are thinking.
ColorThink Pro will display the "H" component of dLCH for images (and colorized shifts for color patches)
In ColorThink Pro's ColorWorksheet, open an image, drop a profile onto the image and ColorThink will calculate the "result" image. Turn on dE. In the dE popups, select delta-LCH and then 'delta-H' in the component popup.
Your image will be shown in gray with middle gray as '0' dH and lighter or darker grays as +dH or -dH values.
In the 2D/3D grapher you *can* show delta-E but it does not break out the dH component into the arc for visualization. An interesting feature idea though.

indeed. We've seen it used in photo, prepress, presswork and manufacturing.

Steve
