How so? As far as I can tell, the ICCv2 spec is very agnostic as to the gamut and dynamic range of the output medium. It doesn't say anything to the extent of "thou shalt not produce any colors outside the sRGB gamut, nor make the white point too bright".
Unless HDR support is supposed to be something other than just the primaries, white point, and transfer function. All the breathless blogspam about HDR doesn't make it very clear what it means in terms of colorspaces.
