Blackheads...?
Inspected two 15GP22 duds under a strong light and came up with zero blotches... until I used a magnifier and found a sea of mini 'blackheads' that are much tinier than a phosphor dot. Can't say for certain that it isn't contamination during manufacture, but it doesn't quite look like that. The other dud doesn't have the blackheads. However, the thick glass faceplates are full of tiny air bubbles and bits of grit; just focus your magnifier inside the glass to see it. And although I can't quite perfectly focus my magnifier on a good phosphor dot plate (because of the CT-100's safety glass) they do seem to be 'blackheads' free.
