In the present study, we investigate the wetting phase behavior of a dilute ternary Bose-Einstein condensate mixture at zero temperature within the theoretical framework of the Gross-Pitaevskii formalism, employing the double parabola approximation to model interfacial phenomena. Our analysis reveals that the first-order wetting transition line and the nucleation line associated with three-phase coexistence intersect at a set of degenerate points, which reside in the parameter space defined by the interspecies interaction coupling constants. Furthermore, we systematically examine the locus of these degenerate points within the space of intrinsic atomic parameters, particularly in the regime characterized by strong segregation between two of the components.
