I'm not following this thread but nice explanation. So YUV in anything other than 4 4 4 is basically "compressed video" ?
Depends on how crazy you want to be with semantics. There is no distribution video format other than subsampled YUV. Typically 4:2:2 without datarate decimation is called uncompressed video. Some television studiom equipment is RGB but anything coming in from the field or going out for broadcast is YUV.
Broadcast video is actually removing information per sample as it moves forward. NTSC and PAL were 4:2:2 uncompressed while ATSC (US HDTV) uses 4:2:0 with fairly lossy MPEG2.
