Is your shaping gain influenced by the modulation format? In this work, only one modulation format is used, the 64-QAM. We compared the PS-64QAM (PS over square 64QAM) and the HPGS-64QAM (PS over GS-64QAM). Therefore, the shaping gain we obtained are from the shaping in both probabilistic and geometric spaces which can slightly improve the performance better than probabilistic shaping only.
