Does particle culling even work?

When I check the values for a procedural, looping particle in 2019.4.20 I get these logs.

It never changes even when my camera is nowhere near the particle.
I tried changing the particle Culling mode to automatic, pause but doesn’t change anything.

Maybe it does get culled and those print values don’t relate but who knows.
How could I debug this?

Those values are nothing to do with culling.
You could try getting the ParticleSystemRenderer component and checking the isVisible property.
