Photography is indeed one of my primary hobbies. Wildlife photography mainly. And I have been waiting years for a replacement for my Nikon D200. The now discontinued Nikon D300 was not enough of an upgrade to warrant a replacement then.
there are indeed many color spaces and you could indeed create your own. the two you cited are indeed color spaces, though bigger than what we use now in HT, rec 709.
For purposes of home theater, we are mainly concerned with the color space of the source material, the ability of the source player to output that space, and the ability of the display to reproduce that space. Then we get into such things as the chroma subsampling that the source material is stored with and the bit length. The concepts are not easy to completely understand and we tend to want all the numbers and spaces to be as big as possible. This unfortuntely costs lots of bandwidth and this is limited by technology and economics.
