Thanks for taking the time to give these nice examples.
So most of the goofing around I’ve been doing on this thread was on my laptop, either during lunch at work or sitting on the couch in the evening. But that screen is not calibrated and also not full sRGB.
However most of the real editing work I do is on my main desktop that has a calibrated sRGB monitor. So I’m looking at things on the calibrated system now for comparison. Interestingly the differences now between the image in the DT editing session using std filmic v6 and the rendered result are basically gone. There are certainly differences between how the live image looks between filmic v6 and v5, but those differences track to the renders as well when viewed using my nice monitor. Same goes for the hacked version of v6 I use- looks the same in DT as in the rendered image viewed externally.
Immediately switching to my laptop and opening up the same renders I just made on my desktop, and comparing them to what I see when opening the raw file in the DT editing session on my laptop, the color differences between the live editing session and the externally viewed renders are back once again.
I think there is no point in posting results, as everyone on this thread is probably seeing something at least mildly different than what I’m seeing unless they are using a calibrated sRGB monitor.
So in my case looking at this image, I think a large part of the reason the foreground flowers in the std filmic v6 image turned significantly more red in my external viewer was that my laptop display is not that close to sRGB where it mattered for this image.
