The seven is always there and never varies so I'm not seeing
anything but seven. I had tried to envision six but the axis are
also bent slightly to accord with a seven-fold system.

I thought of that too but the intensitieare are not diminished
and I have frozen the images multiple times throughout the
recording. The symmetry does not appear to have any voids, but
blocking could be there.

Yes, agreed

My first thoughts were LED helium filled balloons and had bought
some recently for my friends daughter.

The slight rotation could still be adequately explained as the
photographer rotating the camera as he held it. I can still
believe that we are looking at a lens flare through a seven
point aperture, noting that the center one is always brightest.
A thin-film coating on the lens could cause the two order
separation along each of the seven axes, thus filling out the
flare as observed.
