This is very poor. A curve is a geometrical shape plotted on a graph with x and y axes - the whole point about about a gamma curve is what is plotted on each axis. When you explain this, then you have explained Gamma Curves. Your explanation does nothing of the sort and someone's talking head with not a single graph is totally useless to anyone.
