  The absence of a critical nematic phase in the vicinity of the $\rm {SU}(3)$
ferromagnetic point for the one-dimensional spin-1 bilinear-biquadratic model
is demonstrated by means of the tensor network algorithms. As it turns out, the
phase transition from the ferromagnetic phase to the dimerized phase at the
$\rm {SU}(3)$ ferromagnetic point is direct, but not of the first-order. The
transition point features highly degenerate ground states, which are scale but
not conformally invariant, with the fractal dimension being equal to 2. The
conceptual developments in effective field theories - the fractal dimension and
the counting rule of the Goldstone modes - play a pivotal role in clarifying
the numerical artifacts arising from the finiteness of the bond dimension in
the tensor network simulations, which are attributed to a proximity effect to a
highly entangled scale or conformally invariant ground state.
