I thought this was obvious?
It's blatantly a photo of 055#1 footage being played on a monitor. Like most people who follow 055 progress, the pictures and footage of 055#1 are seared into my brain. In fact, here's the original picture without the discolouration:

055#2 is berthed on the western side of the basin and won't be moved for a long time. 055#1 and Yuanwang #? is taking up all of the east side and both require at least 6 months of work. The only free space for 055#2 is the space it's currently at.
This means 052D#16/17 is going to be launched late because there's no free space for it until one of the already-launched 052Ds get delivered to the PLAN.
