Answer
A bad drywall repair is corrected by identifying why it is visible, then rebuilding the finish rather than simply adding more paint. Common problems include raised seams, insufficient feathering, sanding scratches, loose tape, mismatched texture, flashing primer, or a paint color and sheen difference.
The repair may need sanding, removal of unstable compound, retaping, additional finish coats, skim coating, texture correction, primer, and repainting to a natural boundary. If the patch is unsupported, poorly fitted, moisture-damaged, or excessively built up, partial replacement may be more practical. Heavy texture or paint should not be used merely to conceal an unsound repair. Side lighting can make even small surface defects more visible, especially on smooth walls.
