As you may know, HDR is a 64bit definition. ICC is a 16bit algorithm.
I'm not sure what you mean by HDR being "64 bit". Most video streams are
16 bits per component or less. Typical displays are 10 - 12 bits at most.
ICC V2 has 16 bit per channel precision and V4.4 can accommodate 32 bit
per channel floating point profiles.
So any issues with creating ICC profiles for HDR displays is purely about
standards (such as what to regard as your white point luminance level),
not the underlying capability of the ICC profile itself.
Cheers,
