Does added covalent character to ionic bonding make the bond stronger between two ions e.g. AgCl so there is a greater lattice enthalpy of dissociation?

The covalent character of AgCl results in the theoretical lattice dissociation enthalpy being LESS than that of the experimental born-haber cycle according to a few sources (Chem Revise and Chem Guide). This suggests that the increased Covalent character does indeed increase the lattice dissociation enthalpy as it requires more energy to separate the 'ions' in the molecule. Thats how I understand it anyway, please tell me if I'm wrong XD
