I looked up that Dark Energy Pro software.

Its amazing.

As for Grain on optical, I would say it would vary depending on the shot.

For example the Vaseline land speeder shot, is vary bad, and mite benefit from a bit more clean up, so it would not stick out so badly.

I can understand the space ship shots having some ruff Grain.

Its there because of the optical work, but it actually ads to the realism.

It makes it look like old stock footage, like it an old war movie.

Especially when you consider this.
