Can you explain what method you're using to measure blade pitch? I actually just threw a digital pitch gauge on mine yesterday and found the same thing; unequal pitch at stick endpoints.
For flight mode HOLD (TH on, FM switch set to 3d mode), I set pitch on a 0100 flat line scale. At full down stick, I get 13.6 and 13.3. At mid stick I get 0.1 and 0.3. At full up stick I get 12.0 and 12.2.
To double check everything, I changed the pitch curve to a solid 50 across the board. same results, 0.1 and 0.3.
Then I changed pitch curve to 100 across the board. same thing, 12.0 and 12.2.
Then pitch curve set to 0 across the board, 13.6 and 13.3.
So the curves are reading and transmitting correctly. But there's obviously more negative pitch than positive pitch, and mid stick is correct for zero and actually a hair positive. So it almost doesn't make sense. I could bring the swash down to add a little positive pitch, but then mid stick would be around 1 degree instead of zero. Not ideal, but at least the pitch spread would be more equal. I haven't decided yet which to do.
And yes, all 3 servos are dead level in neutral position.
Is this similar to what you found?
