Non the less there will be different appearances on different screens of the same picture and that is what we are dealing with here. The only 'real' way to view a picture to enable you to see the depth of shadows, highlights and the overall appearance, is to have a hard print in front of you where the overall appearance can be see by all those view it. It will be their standard and that is what should be assessed not the electronic trickery used to make it.Neutral isn't a matter of opinion. It should be precisely calibrated, using something like the Calibrite puck and software.
For printing, the "norm" is 80cd/m², 5600°K. Similar for displaying on screens.
If you have calibrated your screen, if an image looks wrong to someone else, it is their screen that needs calibrating.
If you look at images on a screen there will occasionally be a subject which may not be to you individual liking. There may be nothing you like about it, but there is no need to be acidic about it. Be constructive, not ultra critical, and suggest how it may be improved not say something which sounds like a command and it could be considered an insult to their work.
