I would say depends on how much work you want to make for yourself, you could touch up with some non printable caulk or even white silicone around the edge of the window board and just lightly sand the gloss on the wall and repaint that small section of wall.
Did you sand the window board prior to glossing ? How many coats did you put on ? Undercoat ? Primer ? Either way looks like the paint has just layered up on top of the tape and when removed has left the rough edge.
I would usually use caulk around the edges first to give yourself a nice clean edge to work to.
Also looks like your tape was slightly on the sill and not completely on the wall
