Hi-Res Images at Natural Size?

When I include an image in an iPad app I reduce height and width by half, lock the image, and set quality to “good”.  The resulting display in the IDE and simulator does look soft. However, the same image looks sharp on the device. I just checked that again on an iPad Air.

be well,
