  These brief comments on the article in Phys. Rev. B 93, 155116 (2016),
address an inadvertent misrepresentation of the capabilities of density
functional theory (DFT) and of its local density approximation (LDA) in
describing electronic and related properties of materials accurately. The
oversight of some previous LDA results that agree with experiments partly led
to this unintended misrepresentation, in addition to a few assertions relative
to perceived deficiencies of DFT.
