Indeed it is.  The color version is the VT525.

I haven't found the technical manual for VT525, but the user manual 
mentions as one of options in the configuration menu:

"Erase text to the text background color (PC style)"
"Erase text to the screen background color (VT style)"

However, to a very large degree this is all moot.  We have done it one 
way for 17 years, and that is the terminal emulation that is expected 
when $TERM is "linux".  Realistically, if we want to introduce a new 
xterm-compatible mode it needs to be just that, a mode; and then we can 
set TERM to "xterm".
