More pixels is the easiest feature to implement on a display and far far easier than making better pixels. Images would benefit from a much higher bit depth and a much larger colorspace, ideally covering 100% of our eyes' range. The problem is that all TVs (with maybe a rare exception) are only 6-bit and if you are lucky the last 2 bits are well faked. Even professional 10-bit displays are really only 8-bit with the last 2 bits well faked. So changing BD to have 10 or 12 bits instead of 8 would result in zero changes to the image viewed at home unless you were using a professional monitor or a projection system as many of those are 10-bit (probably also 8+2). Increasing colorspace significantly is going to take a breakthrough in display technology. When an HDTV says they have deep color, it just means they can accept the signal and display an image after chopping off the last 4 bits, not that the TV is actually capable of displaying a true 12-bit image.
The best we can hope for now given current display technologies would be 4:4:4 color and video encoding that is even closer to the original uncompressed image. The impact of those would be pretty subtle for most people so I don't expect them in my lifetime. Video compression is about attaining a certain level of quality in as few bytes as possible, not attaining the maximum quality in a fixed number of bytes.
