is
interp1(x, v, x(k), mtd) == v(k)
always true or does it depend on method and/or type of x and v? Followup: is the answer documented?

Yes, guaranteed. interp1 calls griddedInterpolant to do the work and that routine says,
"This surface always passes through the sample values at the point locations."
