100% this. The video has gone up by Ben and seems to support what I found earlier this year in the hot Aussie summer - that the Viofo A229 Pro shut down around the 70/80C mark but the Vantrue Nexus 4 Pro kept on going. My rough testing was done on a car that's steel grey in colour, so not white and not my last cars black.
I'd argue though in that article you posted previously that Queensland isn't the hottest state in Australia, it's more where I am Western Australia where it's a dry heat. But I guess where they're coming from is that most of Queensland is up north towards the tropics so it is pretty humid - couple that with a reasonably hot summer and its stifling! Lol
