I would suspect that the DPS-LAX fares you are talking about, are via North Asia rather than the middle east. Most of those routes are around 9000 mi.
Imagine the 9000 mi ticket is 800 USD, then you'd be buying miles at 8 cpm if you take the 13000 mi ticket for 1130 USD. Not quite attractive is it?
