Nothing to see here. You take photos on a smartphone to share them on social media, and that’s it. Only a tiny minority of phone users would ever ponder the color gamut of smartphones or their color management. Accuracy is not a priority.

Many serious photographers say you must calibrate and profile your monitor, and maybe they’re right. But most camera users in this world enjoy their pictures without getting bogged down by such technicalities.
Levels often seems like a boring old tool in photo-editing programs. Maybe you’d use it to quickly fine-tune contrast by dragging the left and right sliders inwards. But it’s good for much more than that.
