Let me show you some photos of similar problem with Z1.
ISO is above 400. So i thought if ISO is above 400 with flash then there can be haze. Not true. See this pic (reference)
ISO 800, dark room, flash on = no flare.
Is ISO 800 high enough ? no, it can go higher still. See this (reference)
ISO 1600, flash on = no flare
I'm surprised this issue even exists with Z1c because the flash is positioned further away from the lens than the Z1.
