Well maybe, but this is just you guessing.
Nobody knows the necessary level of detail.
Telmo.
Take LSD or psilocybin mushrooms and what enters the brain are
chemical compounds that interact with neural ligand gates. The effect
is a change in the perception of consciousness. Then if we load coarse
grained brain states into a computer that ignores lots of fine grained
detail, will that result in something different? Hell yeah! The idea
one could set up a computer neural network, upload some data file from
a brain scan and that this would be a completely conscious person is
frankly absurd.
But would it be a conscious something...very likely, but how would we know?
