Aval's oriented tree isomorphism conjecture

Let $G$ and $H$ be trees equipped with orientations $\gamma$. For an orientation $\gamma$, let $\chi_G^\gamma(x;q)$ denote the oriented chromatic quasisymmetric function obtained by weighting proper colorings according to the number of oriented ascents. Aval's oriented tree isomorphism conjecture. If $G$ and $H$ are non-isomorphic oriented trees, then

$$\chi_G^\gamma(x;q)\neq\chi_H^\gamma(x;q).$$

This generalizes the tree isomorphism conjecture to oriented chromatic quasisymmetric functions. The supplied text gives no resolution status for this oriented version, so it remains open in this record.
