No, is just lesser quality. Have same content dont worry. You will shocked how much content it will be
"Is just lesser quality" suggests there is a higher quality non compressed version but ,when I asked directly "Is there a way to get the non compressed version?", your answer was no...
Why publish a game where it has to be compressed to release it and name it "Officaially Compressed" with no way to get the full quality version? Why not just call it the "Official" version instead?
