Same for mintty.

I tried `echo "\e[c"` (send device attributes) on mintty 2.8.1 just now and got "4" back ("VT132 with Advanced Video and Graphics").

You can fix that with a pull request to ucs-detect; for example: https://news.ycombinator.com/item?id=45801452

Only if run with `-ti 340` argument. So in general, it's not there.
