Download the original file and zoom it to 100% to get the most accurate result.

So... Just some thought on how future display technology can get the most out of limited pixels (especially for DLP based ones since those got their pixels pretty expensive comparing to other technologies). My thought is, since 4:2:0 color compression is the norm for most contents anyway, wouldn't it be nice if display technology can use that to get more out of existing pixels?

On this pic, every pixel is either on the Cb axis, or the Cr axis. Well, not exactly, but approximately the same idea. Yeah I only used a pair of checker-board color filters to filter out specific colors, and then gamma boost it a bit, and thus both the luma and the chroma isn't really that accurate, but in the future, maybe with optimized matrixes both luma and chroma can be almost accurate.

And this image, when viewed at 100% (using the original file, though I guess JPEG can compress it really well?), on a 4:4:4 monitor (basically any regular computer monitor) you will see a checkerboard pattern, but when view at an angle the color is more or less even. On a 4:2:0 screen though (for example, a TV, when receiving 4:2:0 signal) would make the checkerboard pattern completely invisible unless on area that are very red or blue (again, this is not a completely accurate demonstration) because most of the color information is lost during the transmission.

And this might be the ideal way for pixel shift single chip DLP projector that creates 4K image using only a 2K chip. This way, brighter image can be created with higher gradient steps. 

(And there's a chance that this is already patented, who knows XD If not then... Hopefully in a few years we can get products that uses this technique XD)
