Did Kylie Jenner throw shade at Tyga's baby mama, Blac Chyna?

Me and others who have carried this story are probably reaching but here's what happened. Earlier today, Tyga's ex and baby mama Blac Chyna shared a photo on instagram of her wearing a diamond Rolex watch Tyga bought for her when they were together (pic on the left). That watch is very expensive. And guess what Kylie did a few hours later? She posted a photo of herself wearing that exact same watch - which Tyga also bought for her and wrote "Currently!". Is that a shade?
