Can the iron in well water be detrimental to turfgrass?

Unlikely – unless the iron is extremely high. I mean extremely high not just high. The grass may look a bit brown due to the iron oxidizing (rusting) whil sitting on the grass.

I agree. The iron is not in a form that the plant can utilize (my opinion). Iron uptake is so fast in turf that the lawn would be dark green within a few hours of irrigation.
Conversely, my brother in law plumbed the irrigation after his water softener(to try to keep the iron stains off his house). It worked for his house but the lawn started looking “anemic”.
We replumbed to irrigate with the straight well water. Applied gypsum and watered thoroughly. After a few days of drying out we applied fertilizer and rewatered. What a difference. Unfortunately, he now gets rust stains on the house.
My two cents.
