So should one choose to root their phone, leaving everything as is, will they still receive the OTA update?
I've read in most cases the OTAs don't arrive on rooted phones. However what people seem to be doing is unrooting, applying the leaked version of the update and then rerooting.
Since this is a small OTA, maybe it will still arrive normally on a rooted phone, but I doubt it.
Try the manual process.
