Per Detroit, the condemnation level is 4.5% as long as the oil meets Detroit spec.
I'm glad to see you got a report that includes soot. If it were me, I'd stick with a lab that does so. The soot being over 2% with bypass filters seems very high (I said the same of the insolubles that Blackstone reported), but I guess it may be just the nature of the duty the truck sees. If this is from the older of your engines, it could be due in part to the decreased efficiency of worn cylinders/ injectors combined with the duty cycle.
You're OK so far but keep a close watch until you have a bit more experience and history with the bypass/extended oci setup.
