Close.
A CRT's phosphors will produce a 2.5 gamma curve "naturally" (though I have never seen a "natural" television; perhaps they grow them up in the Orkneys?). You have to use a "gamma circuit" to get to a 2.2 gamma, which is still pretty rare from my limited sample.
Oh, yeah, a pint's a pound the world around.
D65 is the same for all standards. You are spot-on that the path to get there is changes from standard to standard. The differing primary locations for each standard require a different mix to get to D65.
