Old Dune is kind of trippy view that happened once and I can't imagine it happening ever again, not with that budget and quality actors. Its still most approachable of all of Lynch's work. I like it a lot for sort of nostalgic feeling for the 80s vision of the future like from some pulp comics.
New Dune is completely different beast, can't wait till second part comes. That universe is rich for other stories, tv series etc. which seems to be the direction all major studios are moving to.
There are very different kinds of trippyness though. The Lynch version seems quite determined about avoiding that cheesy "bunch of swirling colors" brand of trippyness. Sequences like that exist, but they aren't the trippy bits. The trippy qualities are more between the lines. The TV serial... not so much, that one was more "oh, he's having a vision, switch on the mood light vfx!". Haven't seen the Villeneuve yet, which one would it be?
I think Villeneuve might go more in the trippy direction with the next one.
If you compare (say) 2049 and dune you can tell that the latter has been made to hold the audiences hand a lot (blade runner didn't make it's money back). Now he's sold the concept I imagine he'll have more confidence/freedom with part 2.
