For now, it seems that TruTV is serving as WarnerMedia's launching pad for the edgy and viral, and perhaps a farm system of sorts for its personalities to move up the chain to TBS or TNT (Impractical Jokers getting "Misery Index" for TBS is an example.) The same programming team essentially runs Tru, TBS and TNT these days.
You'll likely see more of this experimentation on Tru until AT&T makes a final decision on its future (there's been talk of turning either that or HLN into a sports channel, particularly if Turner Sports wins PGA Tour broadcast rights)
