Yes, but you can be rude and hostile toward the emperor, if that�s any consolation
You could be hostile to the emperor since launch, and it changes nothing. It only showcases how player agency does not matter, because one conversation he is threatening the protagonist, the next conversation it's back to working together, as if nothing happened.
I don't think the main storyline can be fixed. They would need to add an alternative like Orpheus much earlier, but that would require a lot of new dialogues, while adding new animations is cheaper.
What bothers me, is that they also don't prioritize bugs and gameplay issues. I've managed to completed a patch 5 playthrough just to see the epilogue, and the quest bugs I have reported on my first playthrough were there and the ending cutscene was bugged yet again (which it was for me in all three playthroughs). I don't care about romances to the extent that new kiss or hug animations would make up for that.
