If the current through the LEDs remains constant, the light output remains constant regardless of the voltage applied to the circuit. The diagram doesn't apply with the constant current driver.

You pay your money and you take your choice. If you're satisfied with the cheap ones, by all means, that's what you should use. If you're looking for something better, a few more $$ will get you that.
