Technically, if I'm not mistaken, a video is considered HD when it's 720p or above, so it needs to at least have a 16:9 aspect ration. Just because a video is 16:9 doesn't necessarily make it HD, and just because a video is touted as 720p or 1080p on KissAnime doesn't mean it's not 4:3. A 4:3 video can still be 720p, if the black borders on the left and right side are considered part of the video. So I can't really give you a straight answer, because it really depends on what you're looking for.
For future reference, a 4:3 480p video won't look much different from a 4:3 upscaled to 720p video, so I'd venture to guess you won't be satisfied with the quality of DC until it hits 16:9 at 400-500ish episodes.
