I had some discussion with Alister and it appears that RAW on Sony (even F5/F55) is not truly linear, and I guess that makes sense.
It has to be that if Sony wanted to they could squeeze 14 stops into 12-bit Log RAW. Even BMD refers to their RAW as "Log RAW" on their website. On it they say; DaVinci Resolve can easily handle the 12‑bit log RAW images from URSA.
If anyone actually did pure linear you'd have 1 bit of data representing your lowest stop. Hard to believe anyone would actually do that.
So what did Sony's last firmware that was suppose to address this do? Anyone?
On the FS7 there is absolutely not 14 stops of information in the raw files. As I have mentioned before as soon as you go more than 2 stops under middle grey the image starts to fall apart. Any less and you have lost it. From your uploaded pic...
My real world experience bears this out and so obviously you try to shift exposure to the right as much as possible to compensate, severely limiting your DR
