My ls50s are in a small 12X12 room with a powered sub. I would not use them in a large room.
My 8" and 12" Ohms are both in much larger rooms. Tweets in the standard design are angled in 45 degrees and cross well in front of my usual listening position. Sometimes I listen from a different location with more direct exposure and that tends to make things more like others that tend to have tweets facing forward.
You can also angle out the Ohms for more direct sound from tweets to tip up the treble, but that tends to narrow the soundstage, so its a balancing act. I tend to not do that.
My Ohm 5s have the 4 3 way frequency level adjustments, one in midrange and one in treble. Those adjustments make the big OHMs like the current 5000 very adjustable for personal preferences. There are 4 3 way level adjustments on each speak. That provides 3 to the 8th power or 6561 different combos making it easy to tune them to most any room and personal preference as needed. So I do not really perceive any lacking treble. However, I would note that I have older ears that do not hear out to 20khz anymore like they used to, so its possible others may hear things differently.
For me, the unique lifelike imaging of the Ohms (also mbl) as a whole provide a much more detailed listening experience overall when set up right than conventional speakers. That applies not just in cases where speakers like Magnepan shine, ie very well recorded smaller acoustic works, but good quality big dynamic large scale recordings, like orchestra and big band, which is where I found Magnepans to be lacking prior.
Laid back to me means pretty much what you said. I’ve heard large mbls set up optimally. Those tend to be similarly laid back as well. I’d say its a tendency of omni design speakers in general compared to those that fire straight at you. Magnepans fire forward and back and require a lot of distance to walls, so those are a different story all together.
