Looks like I just found my answer in the source code. This is actually broken due to someone counting the number of characters incorrectly for a strncasecmp in client_config.c. It's done correctly later in the same code. This should be "13" and "15" where it's "12" and "14".
$ grep -n DISPLAYGROUP= client_config.c 466: (strncasecmp(token, "DISPLAYGROUP=", 12) == 0) ||
467: (strncasecmp(token, "EXDISPLAYGROUP=", 14) == 0) ||
667: else if (strncasecmp(tok, "DISPLAYGROUP=", 13) == 0) {
673: else if (strncasecmp(tok, "EXDISPLAYGROUP=", 15) == 0) {
...

I have a xymon server running "Debian GNU/Linux 9 (stretch)" with xymon 4.3.28-2. I'm having bad luck getting DISPLAYGROUP to work in analysis.cfg. It seems to only match on the first 7 characters.
I also see this problem on "Debian GNU/Linux 8 (jessie)" with xymon 4.3.17-6+deb8u1.
Below, I've shown that the display group is set, and that the analysis.cfg file is being parsed correctly by xymon, yet the the svcstatus page only shows the shortest of the DISPLAYGROUP enabled lines.
