Hum. Well yeah. That and the roundie vs rectangular

It's the HDTV that lags the NTSC (around here anyway, and the amount of delay varies from station to station)

You jumped the gun on me. After adding a bunch of screen shots to my site of today's parade, I have yet to put together this little bit about flesh hues reproduced by vintage and modern TV. For the illustration, I prepared these two shots where I tried to make them equal in size in a similar manner as your suggestion. Full screen CT-100 and equal subject area cut from the wide screen HD version. Here they are. Hope it helps. The HD will be sharper. ...Now that I think about it, back in 2002, and for a few good years thereafter, the CBS HD programs had stunning closeups of actors in their 'The Agency' type shows. Now, after beaucoup criticism by media people, who have to keep/make controversy up to keep their jobs, about the harsh look of aging actors, people like Terry Hatcher have obviously had a lot of work done and so are not as visually interesting in HD anymore.
Here's the text I've prepared so far covering the pictures. It's once through the typewriter and so is subject to change or even the 'Delete' key, so read it accordingly.
A ct-100 matrix may generate RBG signals that reproduce better flesh tones on a 15GP22, since the bright, modern phosphors emit a different color than that of their 1953 NTSC counterparts. If so, there could be a difference between the vintage and modern hardware images. That seems to be the case. Here's an example from the 2007 Rose Bowl parade telecast in both ATSC and NTSC. what you see is part of the screen from the digital broadcast and all the CT-100 screen, modified as necessary to produce nearly same size images.
The poinsettias along the bottom of each image serve as an eyeball reference. The cluster of leaves on the right of the analog image match rather well the same plants reproduced digitally. (There's a slight red purity issue on the left.)
Facial hues in digital broadcasts (and analog broadcasts reproduced on a modern set) tend to my eyes to be more red than the same puss reproduced with 1953 hardware.
And here's a link to the other CT-100 Rose Bowl '07 screen shots:
