Redye touch-ups @ the spa?

Some of the textured leathers, like chevre, porc, epsom, vache liegee, can only be touched up so much. Once the texture is worn down, they can only touch it up with a little dye.
 
with box, they are still just re-dying it, right? but since it's smooth leather, the color missing is the only tell-tale aging and dye looks consistent with the rest of the leather when placed on that spot. am i wrong?
i would be fine if a togo bag were merely spot-treated with dye. the pale part is what would catch the eye, so covering it would do the trick.
