First of all, you will need to find out exactly what areas: it is very common that turf near sprinkler sprays or other source of waters start change colors after a while: water residues do build up on the turf fibers which "change" the color to "whitish".
Second, how to determine the color change is a water residue build-up? Simply pull out a piece of fiber, scrap it by using your finger tips, the whitish buildup should come right off.
Can you clean the water residues off? Yes, by using regular non-abrasive cleaners. However, if the sources not being removed, the buildup will come back.
Also, the turf can look whitish if they are matted down which is a purely directional visual reflection and has nothing to do with the turf.
This happens to me as well, I just leave it.
The sprinkler water does the same thing to the real grass, the difference is that the real grass keep growing, and people keep cutting them so they won't show as much.
I have capped off all my sprinklers.
We normally recommend to cap off sprinklers at the time of installation as you won't need them anyway. In situations people leave the sprinklers for other plants nearby the artificial lawn, this can be a challenge.
Water residues is hard to get rid of based on my experiences.
Can't image the efforts to clean off the water residues on a big area of turf, I am too lazy for that.
If the water source not closed off, cleaning the grass will be simply wasting time.
