'40" WS set would have a similar screen height to a 23 4:3 CRT'
I think rather more.
But it is true that 17" 405 is similar visual Resolution to some HDTVs and on 12" the 405 lines is effectively HD quality.
Japan and USA drove the development of HD. It WAS to have larger screens, not "better" quality. The 525 lines looked pretty bad on their 36" and larger 4:3 screens. USA had larger CRTs than were ever commonly seen here and very many projection TVs at home.
The quality of content (in visual sense) is much more variable than 30 years ago. Digital allows trade off between cost & lower quality, almost never "better" quality than best PAL, unless you have HD on a screen with so called full HD, but only a little larger than an ideal SD screen size.
