Universal scalable convergence conjecture for permuton-random sequences

A permuton is a probability measure on [0,1]2[0,1]^2 with uniform marginals; a sequence of permutations is Γ\Gamma-random when it is sampled according to the permuton Γ\Gamma, and it is scalably convergent when its pattern densities converge at every admissible scale.

Universal scalable convergence conjecture. If Γ\Gamma is any permuton, then every Γ\Gamma-random sequence is scalably convergent.

The conjecture would extend the observed scalable convergence of sequences sampled from the permuton ΓV\Gamma_\textsf{V} to every permuton. The supplied text presents this as a belief and gives no resolution.
