That's right. A soundbar that has everything in it (Including the rear speakers) can never match the effects of the sound system, which has the rear speakers placed separately. Sadly, many prefer the compact nature of the soundbar these days and will miss the true effects. Coming to the above recommendations, all of them have rear speakers separately, not within the soundbar. The Yamaha model I suggested is a proper HT with separate speakers for all the channels (FL, FR, SL, SR, C and SW).
