You're darn close. A WELL rounded triangle.

Interestingly, you can make it a perfect circle by connecting the ends of
the 3 radiators with a conductor that forms a circle. ie a 3 phase halo. If
you look at the radiation pattern for this arrangement, or Reg's original
one in free space, the major gain is perpenticular to the plane of the
radiators, not in plane, although the effect is not very pronounced.

The pattern would look like a triangle, so the answer to your question is
no.

"There is a 3-phase transmitter feeding a 3-phase antenna via a 3-wire

The antenna consists of three 1/4-wave horizontal radiators spaced at
120 degree intervals.

Is the radiation pattern in the horizontal plane perfectly
omnidirectional?"
