It really doesn't matter...
The incidence angle of the wing chord is not constant along the span, so there can be no single value for AoA or incidence. Further, the extension of leading- and trailing-edge slats and/or flaps change the effective AoA at any point along the span, and accentuate the washout (higher AoA inboard, lower AoA outboard).
Just use the info given (pitch and FPV), and assume the engineers picked a reasonable datum.
