Let $V$ be an operator System in $B(H)$.By Hamana and Ruan theorem, there is injective envelope $I(V)$ as subspace of $B(H)$.
Thus there is a completely contractive onto projection $\varphi: B(H) \to I(V)$.
By Choi-Effross Theorem, $I(V)$ is $C^*$-algebra by new product $T \circ_{\varphi} S=\varphi(TS)$ for each $T, S \in I(V)$.
The enveloping $C^*$-algebra $C^*_e(V)$ of $V$ is the $C^*$-subalgebra of $I(V)$ generated by $V$.

$C^*_e(V)$ has this property: Suppose that $\psi : V \to A$ is any unital completely isometric map such that $A$ is generated by $\psi(V )$ as a $C^*$-algebra. Then there exists a unique $*$-homomorphism $\pi: A → C^*_e(V)$ such that $\pi\circ \psi = id_V$. 


Question: Let $V \subseteq B(H)$ be an operator system and $U \in U(H)$  such that $UVU^*=V$. What about  $UC^*_e(V)U^*=C^*_e(V)$ ?
