Actually Jumping Flash was one of the more interesting early PS1 games to me and I do remember being pretty damn impressed by it, but to say it laid the ground work for Mario 64, a far more complex and varied experience, not to mention you're comparing a first person game to a third person one, with none of the 3D camera considerations is a highly tenuous claim.
Then take Spyro or Croc for example, as Krejlooc mentioned. You even had Ape Escape eventually. The PSone was more than capable of a high quality 3D platformer and there were many examples of it.
If anything i'd argue that the PSone became a better 3D console once the Dual Shock hit, because with that developers started laying the ground work to properly control 3D games, both first and third person. We don't use buttons to control cameras or aiming anymore. We use an analog stick.
