Why does the D3400 have more DR than the D3500?

What is the truth behind the graph shown? As long as no other figures are shown to support the graph, it is pointless to look at these types of graphs and draw conclusions from them.

So, what bothers you, about the non meaningfull graphs resulting from lab tests.

Take your gear, be happy and enjoy the moments of taking pictures.

These graphs from Photons to Photos have been posted 100s of times on DPR. In fact DPR uses this information themselves. Look up the website if you are truly interested in the underlying data.

Yes, but the question remains how those figures came about, you do not want to know which manipulations they let go in order to arrive at certain "scientific" results.

In other words, you do not focus blindly on such meaningless graphs and do not draw any conclusions from them!

The graph could also have spoken in favor of the D3500.

Maybe he does want :)

"focus blindly" :)

Good observation.

DPR's direct comparison of the specifications does not reveal anything telling. Sony made both sensors according to Wikipedia but the cameras were released two years apart. Who knows?

According to this chart below,

both the D3400 & D3500 cameras,

they share the same Sony sensors.

Maybe Bill Claff can comment on this.

What a mystery (?)
Yes!

Both testing equipment and manufactured products are subject to variation, so there is not necessarily a real difference between the two models.
Exactly this. DXO mark give no idea of variation in their measurements or their testing regime. As i said in the first post maybe they tested the D3500 on a warm day DXO mark is littered with the same sensor getting different scores
 
Although we think of these as "sensor" tests they are in fact tests of the entire system.
The support circuitry outside the sensor as well as the firmware could be (are probably) different.
Temperature can matter but I don't think that's what happened here.

0.28 stops is not very much but it is considered "real" rather than measurement of sample variation.
See Measurement and Sample Variation for some details on that subject.

FWIW, the OP cited PhotonsToPhotos not DxOMark.

As I just posted, PhotonsToPhotos does have an articled regaring Measurement and Sample Variation.

Bill's graphs plot PDR against nominal ISO. If the same sensor is used in cameras that calibrate ISO slightly differently, then the same sensor will get different scores on Bill's charts.
 
Photographic Dynamic Range takes more into consideration than pure DR. It essentially takes separate measurements and combines them into a single easy to understand measurement. Personally I prefer to see the separated DXO data and make my own analysis probably because of my engineering background.
