Detailed angular distributions have been measured for ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$ elastic and inelastic scattering to the first ${1/2}^{\mathrm{-}}$ state in ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$ (projectile excitation) and the first $2^{+}$, $3^{\mathrm{-}}$, and $5^{\mathrm{-}}$ states in ${}_{}{}^{40}{}_{}{}^{}$Ca at E${(\mathrm{}}^7$Li)=34 MeV. Distorted-wave Born approximation and coupled-channels calculations of the inelastic processes were carried out with both Woods-Saxon and microscopic double-folded real optical potentials. No renormalization of the real double-folded potential is needed to fit the elastic data when the contribution from the ground state quadrupole moment of ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$ is accounted for in coupled-channels calculations, otherwise a renormalization of 0.6 is required. Moreover, these coupled-channels calculations matched the phase of the oscillations in the projectile excitation data, while calculations employing a Woods-Saxon real potential did not. The calculations for the excitation of states in ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$ were insensitive to the form of real potential chosen.
