"On a scale from 0 to 10 how accurate would you like BG3 to be in regard of
DnD5e?"
The distribution is clearly concentrated on the right tail. At least whithin the sample, the majority wants the game to be close to the rules.
As would I (was never aware of this poll until now, so didn't get my voice heard). You are correct in that a clear majority wants accurate implementation of D&D rules, but simultaneously most people expressed they were happy with both the D&D rules interpretation and Larian's homebrew. And this was BEFORE Larian actually removed some of their homebrew (like elemental surfaces on most wizard cantrips). So there is some...shall we say logical inconsistencies afoot.
