Your 86.84% is near enough to the absolute ideal worth of occultation.
Unfortunately it'll never remain that good.

I'm using a bit larger sun radius of 700,000 km, and of Venus w/clouds
at merely 5152 km, and the VL2 of 1,014,290 km

Allowing for some give or take from within the halo station-keeping
orbit at VL2:

Solar isolation or occultation of 85% while at VL2 offers 390 w/m2.

ISS average, as based upon orbiting Earth, ISS deals with 780 w/m2.

This means that Venus L2 is actually operating cold compared to whatever
ISS has to cycle between 1370 (+ Earth's reflected IR) and otherwise by
nighttime where it's nearly but not ever zero as it orbits behind mother
Earth that's having to radiate all of it's daytime solar influx (plus
something extra of whatever our moon and humanity has contributed
towards global warming).

I had to guess at the ISS figure of 780 w/m2 because, for some reason
there's no clear cut science on that sucker, as to what Earth
contributes to the ISS thermal energy budget. If anything, I'm guessing
way low on that amount if Earth reflects roughly 36%, as obviously all
of the solar influx has to leave town, or else Earth explodes.

Therefore, a POOF application at VL2 should fly.
