Fantastic set of sequences Duke.
Sexing the adults is very difficult.
The amount of white on the upperparts is not a reliable way of differentiating the adults unless you know the pair well and know the difference between the two by their behaviour etc.
Females are 6% larger on average, which is usually not obvious in the field.
Females usually have a more wedge shaped tail than the males and they have a broader wing at the outer secondaries than the males. The female usually has longer and more ragged "leggings" than the male.
Even Eagle researchers sometimes have difficulty telling the adults apart, even when they know the pair well.
Going on the above criteria, I'd speculate that the female is the one carrying the prey in the pics, but would not put a bet on it.
