I originally bought the eken and when it arrived it had a crack in the screen from one side to the other ( the manufactuer places the devise in its box with the screen facing outward, practically touching the box surface, and then the seller sent it wrapped only in shipping paper, no wonder it didn't make it from China) so I cant give you a side by sine comparison. I can tell you the color on this is beautiful! there is no gradation in the shades of color. it is perfectly smooth. So I would say that this is higher than 256. Now the downside, the only way I know to play toutube videos on this is to install skyfire, which is a browser, and it will not play them in full screen, only a small 2"x3" (estimating) box. I am looking forward to a youtube player in the future, which is inevitable.
