My experience is, if it's visible on the slides, it's going to be visible on content (especially if you watch in a dark room). Like you said, I'm not sure how anyone who calls them self a videophile would not notice this obvious picture defect.
It is quite apparent from his pix that there is vignetting at 1% and 2% ire, when displaying a full white field, however, it is mostly gone by 5%. Given that the vignetting is occurring very close to the panels black limit it highly unlikely it would be visible under normal viewing. To put it another way: how much content do you watch that has sustained
ire's of less than 5% ?? I don't think much ast those are quite dark.. There very well maybe panel's with darkening bad enough to be seen under regular viewing but Thrawn's images strongly suggest his set should not present any issues with normal content. I have included a shot of my set at 5% and 20%. I have never seen signs of vignetting on any content, other than test patterns, on my b6.
Jondo makes a good point:

None of these technologies are perfect, they all have shortcomings. The difference now, in 2017, is consumers have access to test patterns and measurement tools, previously unavailable to them, that can clearly reveal imperfections under the most demanding circumstances. However, many have not used these tools on other current (or previous) technologies so they may not have a frame of reference as to how good these OLED's perform.
