Yeah, sure, this must the reason for the positive outcome. Not because contrary to some edgelord's opinion, most people don't think that PoE is a bad game. But I'm sure the haters can always come up with a good excuse.
If you look at the 2015 Codex GOTY the game received a lot of negative votes, enough to almost push it out of the top 20 in the scoring system used for the vote. If you need a poll 15 months after release to justify or reinforce your opinion that it is a good game, then fine.
Most of the codexers I know that enjoy the IE gameplay quite a lot did not like the Pillars gameplay, for one reason or another (often different reasons). Most of the codexers I see that enjoy Pillars don't like the IE gameplay that much, or enjoy it but not to the same degree that the group that really likes it does.
Me specifically, I have completed only one Obsidian game - Knights of the Old Republic II, which was their first game. I played Neverwinter Nights 2, and never finished it. No game of their since has interested me, and after Pillars, I doubt another one will.
