Especially in the early war, when navigation and targeting tech was worse, yeah, accuracy was a major concern. I think the benefits of night fighting were also more mixed than one might think, due to the increase of air accidents—the accident rate in the war was so high that it was responsible for the overwhelming majority of lost airframes, not enemy fire. If you need more missions to achieve the same effect on a target (because accuracy is worse) and your crash rate goes up because flying at night (enemy activities aside) is riskier than during the day, I could see that making it less of an absolute win even before considering increased collateral damage (which, at least at times, they do seem to have genuinely preferred to minimize)
