(sounds like you need to ADD texture)
If so, this is easy!
At most hardware stores, there’s a texture-spray by Homax. It has an adjustable top for changing the droplet size that sprays out.
>>> Have your repair-spots sanded smooth, ALL dust removed, and lightly primed.
>>> Then do a quick, spiral-motion spray over the patched areas.
>>> Let texture dry, and, IDEALLY…prime/paint the whole wall for the least noticeable result.
