A negative answer follows from this paper of Graham. In fact, my naive intuition on Varopoulos and tilde algebras turned out to be completely incorrect. Hope to find more on that in Graham & McGehee "Essays in commutative harmonic analysis".

Throughout, let $(\mathcal{M},\tau)$ be a von Neumann algebra $\mathcal{M}$, acting on a Hilbert space $H$, with normal semifinite faithful trace $\tau$. In the survey article by Pisier and Xu, the non-commutative $L^p$ space $1\leq p<\infty$ is defined as follows. Let $S_+$ be the set of all p...
