DxO Labs is first and foremost a consultancy. Their business model is
based upon being paid to conduct analysis and optimization of imaging
system performance by the companies that make those systems. DxO is
not an independent journalistic entity or trade organization - it is
a for-profit software consultancy for camera makers. Their product is
called DxO Analyzer, and licensees of this suite can opt to purchase
"installation, training and consulting services."
...
...Products that have received versus not received consultancy and
tuning from DxO Labs are not identified, and so it is impossible to
know which camera has likely been tuned to maximize its score under
the test conditions versus which tends to do well without having
specifically been adapted to DxO's parameters.

This also gives DxO Labs the power to silently "shame" the companies
that choose not to license its software or services.

also, their 'tests' claim what is physically impossible, making them
untrustworthy and their scale is whatever they want it to be, with
newer cameras scoring higher and higher.

Suspicion and innuendo. That's not evidence.

the evidence is quite clear that they cannot be trusted *at* *all*.

their 'tests' claim what is physically not possible. that alone makes
them a scam.

DxOMark controversy is back in the news this week, but the problem
with the mobile camera rating system isn't as simple as manufacturers
'buying' inflated scores.
....
Comment threads suggest something untoward has happened as a result
of OnePlus's recently-announced partnership with DxO

a *partnership* between a camera manufacturer and the company who is
supposedly testing it is very clearly a *huge* problem.

Like a wily student preparing for a standardized test, manufacturers
who partner with DxO, and get access to its hardware and software,
can tune their image processing to ace the firm's synthetic tests
(within the limits of the hardware, of course). As a result, their
review scores are higher when DxO eventually publishes them ‹ because
they've had access to the testing hardware all along. Manufacturers
who don't partner with DxO are at an automatic disadvantage in terms
of their score, even though real-world, outside-of-the-lab image
quality might not be substantially worse. When that happens, as it is
bound to, consumers who put faith in comparisons between scores from
partners and non-partners are potentially misled.
