That yellowing and how its kind of splotchy looks like FMV (fig mosaic virus). All my trees have it and display it with differing levels of severity. Bottom line is that I have found it to not be a big deal. The trees drop leaves during the season when they get too yellow. But they put out new leaves so fast that the trees don't seem to suffer for it.
I have already experienced a couple of dropped leaves so far this year, but the trees all look great, are putting out new leaves and the main crop is ripening!
My VdB produced breba figs for the first time this year. They were okay. They didn't have the intense flavor the main crop has because the brebas don't get enough heat to ripen like that. But it was still a nice surprise to have figs in May
