I feel the same. I went to see Villeneuve's Dune in the theater - the first time I'd been to a movie theater since the equally underwhelming Valerian - and it was... fine, I suppose. I was really disappointed by the washed-out color schemes permeating every shot. It made Arrakis look more like Antarctica to me than the Sahara. The only thing I recall being truly wowed by were the awesome Mass Effect Reaper-like sound effects that accompanied some of the drop ships, but those were more menacing in, well, Mass Effect.
All that said, I do think the visuals of Lynch's Dune have had longer to enter the public imagination. Cryo's Dune game took a lot of visual and musical cues from that movie, and even Westwood's Dune 2 felt like it drew mostly from the Lynch version. For me as a teenager, those became the iconic representations of the Dune universe, and it's hard for me to imagine it looking any different. Perhaps in 20 years people who grow up with the Villeneuve version will feel the same way about it.
Yes, those games! Dune 1 directly uses a lot of movie imagery, down to Kyle MacLachlan's look, and it is also a very unusual hybrid of an adventure and strategy games, I struggle to name any other game that is like it.
I replayed it a few years ago, and it holds up really well.
I still think about the sunsets in that game. Simply flying through the dunes in an ornithopter felt like the most epic adventure. It's such a miss that the Villeneuve movie made everything so white, on a planet with no condensation or cloud cover, where dust storms are a major plot point. Perhaps there is some science-y reason why it could happen that a desert planet would be all white, but it's so bizarre to me that a director would voluntarily choose that washed-out palette when at least to a layperson it seems intuitive that deserts not just on Earth but Mars too tint cloudless skies in glorious technicolor.
You're right there aren't really many - if any - other games like Cryo's Dune. Perhaps the closest experience I had recently was Sable, which is an open world style game where you explore a Moebius-inspired world with several distinct and beautiful ecologies. It's mostly just a slice of life walking sim without any conflict or political intrigue, but visually and emotionally it captures some of that epicness that I look for in Dune adaptations and other Dune-like space operas.
