Video HDR is not a color system per say, its a luminosity system affecting such things as the peak brightness, grayscale, contrast, gamma, etc. Basically, it defines the background "luma" range and not colors. It does tangentially have an effect on color since when you change those values it affects the colors. But HDR doesn't inherently define said values of the colors.
In truth the color has more to do with the wide color gamut (WGC) part of DCI/P3 or Rec2020/2100/etc and RGB/YUV.
While I agree, the way the industry uses the term HDR typically incorporates Rec2020 automatically alongside the higher luminosity range. I've not seen a HDR Blu Ray in Rec709 yet, nor an SDR Blu Ray in Rec2020, tho that doesn't mean they couldn't exist I suppose.
