[Yugioh] Was Yugi's transformation into the Pharoah physical?

It's odd that nobody would comment on his sudden accelerated puberty.

Sort of. The only noticeable change is is hair gets a few streaks of yellow and his voice changes.

His friends have commented his change is personality when duels. But they dismiss it thinking it's just him focusing. There's also the fact the Millennium Puzzle that changes him into pharaoh can affect people's minds.

It probably gives everyone the illusion that nothing's changed unless Yugi or Pharaoh outright tells them otherwise.
