Correct. If using dry yeast making a starter depletes sterols and other nutrients that came packaged in the yeast. It actually can be detrimental.
If using liquid yeast you’d want to build the cell count by creating a starter.
Now, if using dry yeast and making a high OG beer, just use 2 packages as after the time you buy liquid yeast, DME or fast pitch, and the time to create it you’d be close if not better off purchasing 2 dry packets.
In fact, I only make starters when using a saved slurry.
