Sony A7RIII profile
Hello,
I have been using the Sony A7RII for a year or so with CO1, but never found either the generic or the standard profile really satisfying: many of my images looked overcooked, lacking a natural balance. Of course this is partly subjective, but I at least found it strange, that the Sony A7R profiles (which has a véry different sensor), both "standard" and "generic" were IDENTICAL in every way that I could see, to the Sony A7RII profiles.
By chance I decided to try the supplied profile for the new Sony A7RIII, which has a 100% identical sensor to the Sony A7RII, and so I was expecting the same thing to happen again: profiles for the A7RII and the A7RIII should be identical, not?
At least, that is what I was expecting.
Not! The profiles are véry different, to my eyes (on a calibrated Eizo screen) hugely different in especially yellows and blue sky tones. The overall color balance however, is múch better than I could ever get with the Sony A7RII profile, finally a relaxed natural look without (a great deal of it at least) the overcooked look.
NOTE: I am using both profiles with the Sony A7RII, as I don't have the A7RIII, but I downloaded a few A7RIII raw files from Dpreview, and I see much of the same: blue skies looking much more magenta instead of the picture post card blue of the A7RII generic profile. They may have even overdone the shift towards magenta, but still, the profile has a much better overall balance.
The big question: Why are the Sony A7R and Sony A7RII profiles (with two totally different sensors) identical, and why are the Sony A7RII and the Sony A7RIII generic profiles so vastly different, while thése cameras share an identical sensor?
I am now using the A7RIII profile with a few small tweaks for my A7RII, and cannot think of a reason not to. Is there a different color filter on the A7RIII? The sensor stack is supposed to be the same, is it not?

One of my cameras is a Sony RX10 III. I find that if I adjust the WB to, say, Daylight in C1, the sliders get set to Kelvin 5312 and Tint 0. The result looks too magenta. But if I set the camera to Daylight in the first place, the sliders show as Kelvin 5335 and Tint -9.2, and the image looks about right. I raised this as a support case a while ago, but it doesn't seem to have been satisfactorily resolved. It was clear from what Support said that they would have expected their Daylight preset to produce the same result as setting Daylight in the camera, and it doesn't.
My workaround is that I have created User Presets which I call RX10 Daylight, RX10 Cloudy, etc...These have the same settings as you get out of camera (so Kelvin 5335 and Tint -9.2). If I want to manually set a WB preset I use those and not the one in the C1 drop down list. It only needs setting up once - just shoot one image with each of the presets in the camera and note the numbers that show up in C1's WB tool.
I had hoped for an improved profile in a newer version that set the Tint about right compared with the camera setting, but it hasn't happened yet.

That sounds like a bug actually.
The shift to magenta that I refer to with the Sony A7RIII is not due to white balance implementation btw, but a shift of the blue colors of particularly the sky away from the overly optimistic blue skies that you get with the A7RII profiles. Which is a good thing, although they may have overdone it a bit. I find the A7RIII profile very a-typical for CO1, but a definite improvement: switching back and forth between the A7RII and A7RIII profiles shows just the degree off overcooking the color with the A7R/A7RII profiles. The A7RIII profile gets you much closer to a neutral start i.m.o.
