This is a very uninformed opinion that I see very often. In bebop, LH can be deceptively simple (but actually rhythmically it's not so simple). However things have dramatically changed, Brad Mehldau who's a foundational modern jazz pianist, probably the most relevant one after the last Big Tree (Hancock, Corea, Tyner), popularized things like LH counterpoint in jazz. Some of his arrangements if you watch them in mute, you could thing he's playing a Bach Fugue almost. The amount of pianists that followed this style after the 90s, is hard to keep track of, probably every single relevant pianist took things from brad, and LH counterpoint was one of them (a big one there too was Fred Hersch, who heavily influenced Brad).
Then, I recommend you to check out what Sullivan Fortner is doing. Probably the next really heavy one that has managed to push the jazz lang forward after Brad.
