The modified valley version of the Delta square conjecture

Let $n,k\in\mathbb{N}$ with $k<n$, and let $\mathsf{LSQ}'(n)^{\bullet k}$ denote the partially labelled square paths with $k$ decorated valleys. For such a path $P$, let $\mathsf{dinv}(P)$, $\mathsf{area}(P)$, and $x^P$ denote its diagonal-inversion statistic, area, and monomial weight. Modified Delta square conjecture, valley version.

$$\Theta_{e_k} \nabla \omega(p_{n-k}) = \sum_{P \in \mathsf{LSQ}'(n)^{\bullet k}} q^{\mathsf{dinv}(P)} t^{\mathsf{area}(P)} x^P.$$

The source refers to this as the square analogue of the valley Delta conjecture and points to Iraci and Vanden Wyngaerd for its definitions and prior formulation. Its status is not resolved in the supplied source.
