Indeed. Some scalers are certainly better than other, but there is no scaler in the world that can retain a hard edge with even the slightest of scale, unless the pixels are exactly doubled. (1440p) In some ways, scaling so little, from 720 to 768, is even worse than a much larger scale, because theres not enough room for the sharp edges be well interpolated.
Its very hard to notice scaling in action on a photograph, especially motion video, but any source with hard edges like a video game without AA, or menu text etc, definitely suffers in the process.
