Apple is pretty bad at testing, they released the first Retina MBP with ghosting that remained for a minute or even more (I had one).
I use Apple products a lot, but one thing I learnt many many years ago, is never buy the first of anything new they do. Most of the time it will be fine, but when it’s not it’s just bad.
I also had one, for probably 6 years or so, and never experienced this.
