  We consider the four-point function of the lowest scalar in the stress-energy
tensor multiplet in $\mathcal{N}=8$ ABJ(M) theory \cite{Aharony:2008ug,
Aharony:2008gk}. At large central charge $c_T\sim N^{3/2}$, this correlator is
given by the corresponding holographic correlation function in 11d supergravity
on $AdS_4\times S^7$. We use Mellin space techniques to compute the leading
$1/c_T$ correction to anomalous dimensions and OPE coefficients of operators
that appear in this holographic correlator. For half and quarter-BPS operators,
we find exact agreement with previously computed localization results. For the
other BPS and non-BPS operators, our results match the $\mathcal{N}=8$
numerical bootstrap for ABJ(M) at large $c_T$, which provides a precise check
of unprotected observables in AdS/CFT.
