I agree that Darcy is likely to inspire awe, reverence, deference much of the time, but would that really apply 'of a Sunday evening when he has nothing to do'? From the description it sounds to me as though he becomes obnoxious when bored, more in line with awful. (Unless, perhaps, he extemporaneously and dramatically quotes Scripture when bored!)

The paragraph that follows suggests he is awful rather that awe-ful: Elizabeth thought she could perceive that he was rather offended....Miss Bingley warmly resented the indignity he had received....
