No. This line does not tell you much.

Easy way to check for DRi3 is to run "glxinfo|grep buffer_age"  ... if
you have to lines in that output you'd have DRI3.

Intuitive. :)

Well that's the easiest thing I could think of that doesn't require
jumping through hoops ... you could use dri3info, which isn't
packaged.

But you can do:
wget https://cgit.freedesktop.org/xorg/driver/xf86-video-intel/tree/tools/dri3info.c
gcc -o dri3info dri3info.c `pkg-config --cflags --libs xcb-dri3
x11-xcb xrandr xxf86vm libdrm`
./dri3info

Should be:

wget https://cgit.freedesktop.org/xorg/driver/xf86-video-intel/plain/tools/dri3info.c

I'll note:

# glxinfo|grep buffer_age
    GLX_EXT_buffer_age, GLX_EXT_create_context_es2_profile,

# ./dri3info
Display ':0'
        Unable to connect to DRI3
