This is not soon after takeoff when PF should keep head down on the primary instruments
Boeing recommend engaging the automatics asap after take off. This allows the crew to complete priority items such as the after take off checklist. Refer to FCOM Normal Procedures -Take Off Procedure - "engage the autopilot when above the minimum altitude for autopilot engagement". It doesn't take Superman to fly the aircraft manually and still call for the after take off checklist as soon as the flaps are up and the leading edge lights extinguished. In fact the flap indicator and its associated leading edge devices indications should be a vital part of the PF's scan coverage to ensure limit speeds are not exceeded.
