Hey! Both files are actually the same version of the game. The reason the version numbers differ is that itch.io's butler tool maintains a separate upload counter for each channel, one for the raw PS-EXE and one for the disc image. The PS-EXE channel had a few extra CI pushes early on (toolchain fixes) before the disc image channel even existed, so it's at a higher number. But the game code itself is identical in both.
