@ FE Hoppy,
sorry, I don't fly an aircraft and don't have access to an AFM.
The B777 Ops manual doesn't support your assertion.
Can you give an example?
P.S.
Have just looked at the Boeing presentation for the B737-800 linked in Vilas' post #22 above.
Page 18 shows that for that airplane there is an increased gradient at the lower actual temperature, but that is due to a higher thrust, not the difference in TAS.
