Yeah, i too believe there was some sort of tarp put over the scaffolding, making everything appear bulkier. Measuring ratios of same lengths on two images, the earlier image (with scaffolding visible) shows the sail being some 10 percent of the overall length from visible tip of sub to end of tails, while the later image (with possible tarp over the scaffolding) shows little over 13% for sail's length, compared to the same length. Height to length ratio of both seem similar, 45 vs 44 percent, indicating scafolding on top of the sail as well. Which, frankly, was already hinted in the initial image too. Bottom line - it's no sailless sub. However, compared to 093A, the sail is much smaller. And even compared to US Viriginia class, it appears something like 30% less tall, while being as long.
