DPreview studio test scene / shutter speeds

Just came across this interesting thread about ISO, SOS and REI. Was news to me.

So go to DPR's studio test scene and check the shutter speeds at ISO3200 / f/5.6 in JPEG mode:

Canon EOS R: 1/1250 s

Canon EOS 5D Mark IV: 1/1600 s

Fujifilm XT-3: 1/1000 s

Olympus E-M1 Mark II: 1/1000 s

Seems that indeed Fuji and Olympus have a different interpretation of the ISO standard.

Interesting: Canon's FF mirrorless cameras (both R and RP) are ~1/3rd stop "slower" compared to their DSLR cousins, in JPEG mode.

Now, switch to RAW .

Canon EOS R: 1/1250 s

Canon EOS 5D Mark IV: 1/1250 s

Fujifilm XT-3: 1/1250 s

Olympus E-M1 Mark II: 1/1250 s

Now, all four cameras meet at 1/1250 s.

This is where I am stuck.

Question:

Is the lighting in DPR's test scene constant?

Sometimes there is a remark like "lighting adjusted to 9EV" in the [i] field, but not in this case.
