What kind of information?
Dipole surrounds, when you sit in the "null" (between the two drivers with the sides of the speaker facing your head) creates a "nebulous" like (where is the speaker at?) kind of sound. These were considered more or less ideal for Dolby Pro Logic type sound and a fair way of simulating a large array of surrounds for 5.1 (as if your entire side wall had a few rows of surround speakers) for 5.1, but some prefer the monopole or bipole sound for 5.1 as it images sharper. For Atmos/X, dipoles aren't typically recommended, but some people still prefer that type of sound and not every movie you watch will be Atmos/X (although you can use an upmixer to approximate a more immersive sound). I personally wouldn't recommended dipoles for an Atmos/X setup.
Bipoles (which with some speakers can be one and the same as some speakers, like some models PSB makes have a switch on the speaker to select dipole or bipole operation) in the same position sound much more easy to locate/pinpoint sounds, but I think still more spacious than a monopole pointed right at you. These can work OK for Atmos/X and if you're in a tight space, they might work better than a monopole (I used to use Def Tech BP2s about three feet back from the rear wall with the null facing the couch area in my previous house and they sounded pretty good for 5.1 there, I think (couch was against the back wall). You don't want to put them right up against the back wall, though as the rear driver still needs at least 12 inches to sound OK, IMO.
Monopoles can typically go against the back wall and you can angle them towards the listener. They can "hot spot" if they are too close, however. The only way to be sure, since the room/setup affects things and it's still subjective to some extent as to which sounds best is to compare them, really.
Also, if you put angled bipoles behind you or in front of you (where the null mounts on the wall and the drivers face angled towards the listener front/back, they kind of act like a dual set (array) of monopoles (e.g. I use PSB S50 speakers between my first and second row for top middle height speakers with angled drivers facing the front and mid/back rows. These then (more or less) image similar to having two sets of monopoles, one for each row (as if you had two sets of surround speakers playing the same thing beside each row). The main reason for this in my room is I already had a pair and I then only needed one pair to cover all three rows for top middle height speakers. A single pair of monopoles with good off-axis dispersion would sound similar, IMO (e.g. I use two sets of side facing monopoles for the "bed" side surround speakers, one between each row and front wides between the mains and front row (surround #1 between side surround and rear surrounds). Both methods can give good coverage for multiple rows.
Personally, I think either monopoles or bipoles to the sides or just behind you listening couch would work best in your room from what you've said thus far. You'd probably have to compare and angle them around a bit to see which you like best.
