Ambiguity regarding Ever-grasping Vestments synergy

Do Skeletal Shieldbearers summoned from the —
Ever-grasping Vestments ‘Wall of Skeletons’ legendary perk benefit from summon related synergy passives?

For example if I have Summon duration+16%, does that apply to my new bone-wall effect?

If not, should it?

If it does, couldn’t this aspect be made more clear via a similar summon icon visual under the health bar, as skeletal champions and mages already benefit from?
