I do compute the solution at many points along the profile, and while Ex and Ey

point_value function for z component for Nedelec elements?
It's possible (any software has bugs) but I think that's not the
likeliest of explanations. Lots of people use that function, so it would
surprise me.
You can test this by just writing "something" like that function
yourself. For example, you could just have a loop over all cells and
output the solution at the quadrature points on that cell using an
FEValues object -- in the simplest case, just use QMidpoint and then use
FEValues::get_function_values() to obtain the value of the solution at
the midpoint of the cell.
Compare that with what you get in the viz output and what you currently get.
