Thanks for the technical explanation. I am a retired mechanical engineer with 10 of my last years designing printers. They were monochrome, but still I understand some of this.
My prints and screen have a wonderful match. Perhaps because my color sensitivity is not as well developed as others. The issue I always had with printing was brightness. The print was always too dark. I had a custom profile made for my paper that lightens the print to match brightness when I use 150 for monitor.
The real issue for folks who post on the web is the fact that there are so many standards or lack of standards.
Not everyone uses calibrated monitors or views in a color aware browser. I know better but still use chrome because of its speed. But I switch to Safari for critical viewing.
Worse yet, people use monitors that change drastically with viewing angle. My laptop for example.
I have seen images that are garish and oversaturated when viewed on my WG monitor in Chrome but which look fine in Safari. I have been told the reason for this is because the out of gamut colors are randomly assigned in a non color aware system. Whatever the reason, I have seen it
But even for a calibrated system, you have values to choose for calibration. It seems to me that D65 and 2.2 are pretty settled. But I have never seen a standard for brightness.
If I use 120 as I once did to get decent prints, my web images would be to bright. This is why I changed to 150 and got the special print profile. It was to allow setting my monitor to 150.
Not knowing what other users were using for brightness, I had to guess at this. But I knew that 120 was probably on the dark side and that people who used defaults might be up in the 180 range, I choose 150 as a sort of compromise.
I never had trouble with 120 viewing. I work in a dark basement with one 40 watt screw in florescent blub overhead behind me. I do critical viewing with an Ott lamp.
So what would you hazard is the proper brightness for post processing for web viewing?
