Yes...also correct!
You're right but there is some "neutralization" in play, in 1st gear the rotational intertia is high, but seen the higher drive axle torque, the acceleration of the car and longitudenal acceleration is also high. In 6th gear both are much lower and stay relatively balanced. Consequently relative loss is rather constant.
But when you find here an argument to shift up a bit earlier, I can only confess you're 100% right! So when you read the torque curves and factor in the transmission reductions, you need to correct with rotational mass inertion (of the engine and all following rotational parts until 1st ax in the transmission, since the remainder, as from 2nd ax, rotates at the speed of the wheels and is not listening to engine RPM).
