Or Brisbane whose DTS were broken on release and has apparently yet to be fixed, or the stuck early Intel 45nm DTS, or their wildly changing Tjmax values.

Since ambient should be around 20, I think 28 on idle does say a lot. Especially if you consider that both 9850BE and 6400+ idle with a TRUE where like ~30 on stock with ~20 ambient.
It means very little without knowing the accuracy of temperature sensor; if there was a power consumption figure then that could corroborate or reject the idle value.
