Quasi-isometric embeddings inapproximable by Anosov representations

We construct examples of quasi-isometric embeddings of word hyperbolic groups into $\mathsf{SL}(d,\mathbb{R})$ for $d \geqslant 5$ which are not limits of Anosov representations into $\mathsf{SL}(d,\mathbb{R})$. As a consequence, we conclude that an analogue of the density theorem for $\mathsf{PSL}(2,\mathbb{C})$ does not hold for $\mathsf{SL}(d,\mathbb{R})$ when $d \geqslant 5$.
