I was under the impression the "teletext" style ones still used teletext encoding, not EIA-608? It's basically just a data steam containing a single page of teletext rather than a whole magazine? AFAIK Sky Digital uses this approach (at least for SD), with a more modern looking decoder, and it certainly has colour support at least[1].
[1] Although DVB can contain a full teletext stream that can be reinserted into the SD analogue VBI by the receiver. Sky boxes supported that so on some channels you could just go to ye olde page 888, although I haven't a clue if any channels still do that (I don't have an old SD Sky setup around to look).

That's correct - 608/708 is North America only, and UK/Europe could use OP42/47 teletext for simple captions (not whole magazine), and/or DVB (mostly language translation).
