We put the camera head to head against the Alexa and have serious control tests built into Resolve.
Having tested the Canon C cameras, various Panasonic, Red cameras, etc., all using this same methodology I'm confident the color is consistent at the (ahem) 'dneg' stage. We work with folks who have developed LUTs for multiple platforms to emulate various stocks and have had good results consistency-wise.
Skin tones have a decidedly Fuji film 'metalic' feel to them. Other earth tones witch seem equally over saturated above 60% luminance (especially for those of us more used to film's tendency to desaturate at higher exposure levels).
The camera has it's plus side, but it's still far more painful to work with than an Alexa given the horrible menu setup, etc. It's a good camera, but it's still designed like a video camera and despite a wealth of buttons to control the camera, jump into auto everything modes, etc. setup is a pain, and switching modes is a pain. If you think this is a Cine camera, it's not, it's a video camera with progressive cine-like features.
I can change shutter angle, framerate, etc. an Alexa in 10 seconds. With the FS7 (and all the other Sony cameras) it's down into this menu, over into that, up over here, scroll to that.. just a major PITA and VERY prone to error if your AC isn't a Sony expert. Don't get me started on all the other little gotchas. To me, working with a crew, I want equipment that helps reduce errors, not encourages them. I don't think Sony's ever understood this.
The EVF also interferes with a lot of support equipment that's close by. Mattebox stages that are top load will require the EVF be moved away to swap filters, the follow focus is very cramped by the EVF meaning every lens change this is an issue. The image in the EVF is good got LCD, but it's nowhere near the image you get from an OLED and the length is a real problem, burn issues be damned.
We tested with Cooke S4's and even the 75 was just cramped as all hell, so the operator will be wanting to re-adjust the EVF every time you have to change lenses, filters, etc. Some aftermarket support options for the EVF will help here, but that's going to be an add on.
For Sony the camera is a 7 where the earlier cameras like the 700 were a 4 at best for ergonomics, but their menu system and the EVF will have anyone using it for serious production work wanting.
