I enjoy your analysis :-) I don't know about "could care less" conveying the semantics - I genuinely paused when I first read it to work out which meaning it had. Let's saying "caring" goes 0 to 10. "Could care less" includes everything from 1 to 10, assuming integer granularity - it's very much the right hand side of the scale, anyway. Only "couldn't care less" covers that 0 rating. So - perhaps it's terrible in conveying semantics and only context/tone imply the disinterest being communicated?
