I'm having trouble imagining by what stretch of the imagination you could call decision theory an account of reality and then declare it to be false. What does a universe look like in which decision theory is 'true'?
If you define “best way of deciding” simply as “deciding according to what DT says” then that is the best way of deciding. But if no physically realizable agent can do that, this is meaningless.

It becomes meaningful only if you can argue that approximating DT is both (1) practical and (2) approximately optimal according to some criterion other than “approximates DT.” That is true in some situations, and not in others.
