from what we all learned when we first met the photography world, a bigger sensor = wider dynamic range.
but as its seem in real world it isn’t the case,

and I don’t talking about pictures now because I don’t know, but in video the dynamic range of the full-frame a7siii the aps-c xh2s and the 4/3 gh6 are more or less the same.

what do we missing? Does the difference in sensor size doesn’t exist (for DR) because of a weaker link in the chain (like a processor or something ) ?

What you’re missing is accepting a gross generalisation as being true in all circumstances.

Many factors affect the DR of the sensor, even before it’s gets to post capture processing (which is what most people talk about here)

All things being equal, a larger sensor could afford a smidge more DR, typically because you tend to be oversampling the noise, so the perception is that it has more DR. I qualified this on a million ways that mean you can never compare apples to apples.

Some cameras are also sensor optimised for DR and some for stills.  You can’t take the stills as the same DR number either.
