In the headLESS case we should never be here, since this is initializing the devices that don't exist in that case.
In the headFUL case I would prefer to keep the existing non-debug behaviour that we soldier on and try to do something sensible. Line 204 has a comment about a case in which GetDIBits really did fail and there's code to cope. I am writing specifically about GetDIBits.
