B767 first officer reported receipt of a revised route clearance via cpdlc during taxi out that was ...

Narrative:

While taxiing out; tower informed us that we had a new clearance and to contact clearance delivery on our #2 radio and monitor tower. Just prior to contacting clearance; someone on tower stated revised clearance coming via cpdlc. We received the clearance within seconds of hearing that transmission. We uploaded the new clearance using the load prompt; re-entered the departure rwy; SID; arrival rwy and STAR. However the concern with the procedure is that there appears to be no way of verifying that the new uploaded departure is accurate. When we reviewed the new route we did notice a change to the first fix. However; unlike our procedures at the gate where we verify the clearance against our release there is no way to do this using this procedure when a change comes via cpdlc. Did the fight crew miss something? Or is this an accepted risk that the crews/company are expected to take?
