We show how to improve the semicontinuity bounds in [1] by optimizing the proof of the basic technical lemma. In this optimization we apply the modified version of the trick used in the resent article [2]. The most important applications are the semicontinuity bound for the von Neumann entropy with the energy constraint and the semicontinuity bounds for the entanglement of formation with the rank/energy constraint.
