I think that there's probably two levels of the jutsu with the same seal and name, the difference lying in better chakra manipulation and how much thee is to throw into it - the most basic, academy-level version is only a genjutsu, with no real-world effect, the graduate/genin level version is a combination genjutsu/ninjutsu that warps space around the user to give them the gross physical characteristics of the person or object they turn into while the genjutsu layer takes care of details of appearance and texture.
Then, there's Naruto's Orioke no Jutsu, which in canon is probably the second, but in most fanfic is a real, complete physical restructuring, which has been explained here as dumping wasteful amounts of energy into it with no more direction than "Make me a hawt chick!" and a predisposition to ninjutsu rather than genjutsu.
... and are we pathetic or what, arguing the nature of a specific ninjutsu? Oh well, being easily amused means seldom being bored.
