ABSOLUTELY.
So much less stress for me, and much, much safer.
My late-neighbor was run down on the job twice, at least the second time, in hi-viz, but in the rain. Second time...brain injury and metal in the hip, a limp, and chronic pain.
I'm much more concerned about hi-viz with reflective stripes than company logo on a shirt. Any time you unexpectedly are on the road, or expectedly on the road, you're ready, as well.
We work/ travel in the dark somewhat, and pack-up with lights in the winter, as best of times you're lucky to have 9 hours of solid light in the dead of winter.
I'd put some hi-viz stickers on top. It's amazing how much that black helmet reduces your birds'-eye hi-viz profile.
One needs to consider the angular size of things. The sun and moon each take up Only 1/2* of size in the sky. A person, from 60-80', IDK, but its very small. With your high production rate, it's easy to cut corners, and you're at the mercy of your climber. I'm one to stack odds in my favor.
A low-viz helmet is like knee-length chaps.
