Just for comparison, years ago those Korean companies selling A- quality IPS panels from LG (rejected stock from Apple displays, mostly, that didn't make it in) would give a similar disclaimer. Given even panels of that grade could have them (and I had seen user photos of such dead pixels, although not on all units) this doesn't seem out of the ordinary given the price point.
