My question does not exclusively talk about color nor does if reference printing, it's about forum users judging or making suggestions concerning the technical aspects of a particular post/photograph using a monitor that may or not be properly calibrated. I would assume that very few if any of the users on this forum are going to print a photo first and then comment to the author.
It doesn't matter if they are viewing a photo that you created on a calibrated monitor, and they are viewing it on a calibrated monitor because calibration is a closed loop system designed for printing. That means you calibrate your system to your use and the calibration changes with room light, with color of walls, with type of paper, with printer. So I have my system calibrated, fine - but that doesn't mean that a photo from your calibrated system will look correct on my system.
You then have to factor in - what do you like for color, vs what I like for color. I used to run a professional photo lab. For every client we had a master target that would be used for color balancing their orders. Some would like their prints on the cool side, some liked them on the warm side, some liked them with a red tinge, some liked them with a green tinge.
Even where you hang the final print makes a difference on color balance. That's why in my top end portraits for clients, I actually go to the house, with a full sized proof print, hang it on the wall where it is going to be displayed, and then adjust my color balance from there. A print displayed under tungsten light will look different than the same print displayed under florescent light, or sunlight.
It is because of all of these variables, that I don't even attempt to correct a file in house if it is going to an outside lab. I let them do the color balancing on their end because even with their print profile, it's a hit and miss game.
At the lab we used to have a set of 4x6 prints of a Kodak Shirley Neg - google it for more detail. But on the print was a big grey spot, that you used to calibrate your system too. Nice big expensive densitometer so that we could nail that grey card perfectly. But in this deck of 4x6 prints of the standard Shirley neg, we only had one that was correct according to the machines. Then we printed it out in 5 point increments in all different directions all the way out to 50 points out in all directions, including density. When a client a new client would come into the lab we would take that deck of prints and lay them out in front of the client and ask them to pick the best color by their eye. On the back of each print we had recorded the actual settings of that print, so we would flip it over, right down that number, and then shuffle them all up and do it again. We would do that five or six times. We never had a single photographer that would pick the same color twice.
And that was dealing in a closed loop system where everything was calibrated, and final images were all viewed under very expensive calibrated daylight bulbs.
So back to calibration of a monitor - just because it's good on your calibrated monitor doesn't mean it will look the same on my calibrated monitor. And me looking at it on my monitor and telling you that it is out in any amount in any direction is nothing short of impossible. And a waste of time. The only way you can ensure that your color is accurate and consistent is to have a new grey card that is being lit by the same light as the subject included in the image. Why a new grey card - because even the color of a grey card changes over time.
Now I know that flys against what everybody thinks is correct. But very few have actually got the real experience to understand what they are talking about. Most is just parroting back either what they have read somewhere, or what they have been told by somebody else that really doesn't understand.
