I seem to remember reading they used one of those machines to colourise some Doctor Whos in the early 90s, mixing the colour from off-air recordings made in the US with a black and white telerecording, and using those machines to warp the off-air to match the distortions of the telerecording (otherwise the colour wouldn't match up).
Yes - they used CLEO to warp the chroma (from NTSC UMatic off-air recordings of standards conversions) back onto the luma from B&W 25fps film telerecordings. The Telerecording process altered the picture geometry, so Charisma was used to match the chroma and warp it back.
Some of those restorations may now be obsolete as chroma-dot recovery (recovering the PAL subcarrier dots from the B&W telerecording) may have been used for more recent releases of the same stories (and the maths of the chroma dots also allows the geometric distortion introduced by telerecording to be deduced and reversed)
CLEO effectively killed the market for Mirage (such that it was in the UK), though I don't think that market was huge (though it was sometimes used in Harry suites). I don't think either the BBC or ITV owned a Mirage - when LWT used it on their Channel Four Friday/Saturday Night Live series, they used one in a Covent Garden facilities house and had to book vision lines both ways to use it (and cameras didn't get tallies as a result...) That said - when Sony demonstrated their System G DVE (a lot of the IP for which went into the first generation PlayStation) - but couldn't ship it, Quantel got a lot of interest in Mirage again...
The market for off-board DVEs has almost disappeared now (in fact it may have entirely - DVEous was the last I was really aware of and since Ross bought Abekas/Accom I'm not sure it still exists) since vision mixers introduced integrated DVE/DME/DPMs (Sony used to sell DMEs as external, but integrated, options - but they are now physically boards within the main mixer crate these days) None of the current integrated Sony or GVG DME/DPM/DVEs can do what Mirage or CLEO can do - letting you design your own 3D shapes - so we could do stuff live in the 80s that we can no longer do live today (though that may not always be a bad thing, it is a shame for some situations)
