Yes they do, but many sets promoted as 'HD' capable don't limit the chroma bandwidth as NTSC sets do on the composite input.

Even my 6 year old HD RCA F38310 CRT set http://www.hometheatermag.com/crtdisplays/95/
passes the Tektronix chroma bandwidth test signal
showing that it provides at least 80 lines of chroma resolution on the composite input.
