What a dumb thing to say! Doesn't this i***t understand TTL metering or vignetting?
Another mega dumb claim... this light loss problem is in the corners. Increasing the sensor gain would lead the centers to overexpose.

Thanks for your answer GTW. I understand a lot of information is missing in these articles and that Mark Dubovoy might be telling bullcr@p but I'm still giving *some* credit to DxO lab people, not much though. I assume they should be rather educated people, at the very least on the software engineering side, and that they do have some scientific education on proper test procedures. I'm guessing they're just not very good at reporting (which is also a part of one's scientific education I agree) and that even though we're left clueless with one guy poor analysis, there must be some things to investigate (caused by light angle or not). The practical consequences.
Now one could argue about the relevance of such findings IRL, but then, one could discuss the relevance of the slimmest form of pixel peeping. Who sets the limit?
Also, a much more constructive move would be, IMO, to structure an open reply to highlight the shortcomings of their "draft" and request a of their methods.
Greetings,
