In this instance, regardless of the differences in accuracy that can be measured, who's going to be able to tell? This isn't some landslide blowout on the Apple side to the point where it's immediately noticeable. At this point, all I could confirm is that on their absolute color accuracy test, the iPhone has the record. That doesn't mean that other tests regarding accuracy overall aren't in the S8's favor. What I can say is that devoid of all of that, considering how close it would be on either side, the other factors play heavily on which one performs better overall. That goes to the S8. Having choices on how you want your display to act is better than not having them at all.
I think I get what you're saying and I don't want to put words in your mouth, but here's how I interpret what I think you think you're saying: "I know it's less accurate, but it has other things I prefer so it is better". And if that included a "for me" at the end, it'd just be an opinion and we'd all say cheers and godbless

So between panel A & B, A > B is either true or it isn't. And I like A more than B is either true or it isn't. But those statements are not related to each other and do not influence each other, at least not in the latter influencing the former. Depending on the degree, the former could easily influence the latter. See where I'm coming from?
