These solutions, naturally, coincide.
DSolve[{y'[z] == z, y[0] == 1}, y[z], z][[1, 1, 2]]
Evaluate[DSolve[{y'[z] == z, y[0] == 1}, y[z], z][[1, 1, 2]]]
(2 + z^2)/2
(2 + z^2)/2
But, surprisingly, the corresponding graphs are not identical:
Plot[ DSolve[{y'[z] == z, y[0] == 1}, y[z], z][[1, 1, 2]], {z, 0, 1}]
Plot[Evaluate[DSolve[{y'[z] == z, y[0] == 1}, y[z], z][[1, 1, 2]]], {z, 0, 1}]
Is it a feature or a problem?
