The Fall is colorful along the lines of The Fifth Element and The Cell.
Happy birthday!
If you liked that you might also like Life of Pi.
I bet City of Lost Children would be amazing too (dunno if it is available in 4k) Much darker than the other two but still visually amazing.
ETA: It seems City of Lost Children in available in 4k Ultra HD but at $55 on Amazon it is terribly expensive.
I’m seeing IMAX Enhanced or something like that in streaming movie descriptions. Not sure what it means. The movies do look pretty good that way, but so do plenty of 4k movies.
There was a recent release of Lawrence of Arabia on 4k that looks amazing.
Don’t forget there are digital streaming options for 4k. They’re going to have some compression, and aren’t nearly as crisp as a physical disc - but they’re a lot cheaper and accessible.
What sort of soundbar did you get? I upgraded to a Sonos Arc that had Dolby Atmos, but I can’t say I’m super impressed with it (I don’t get a ton of opportunities to really crank it up to take advantage of it, though). My audio recommendations are to 3:10 to Yuma (specifically the train scene at the end), Blade Runner 2049, Top Gun: Maverick, and 1917.
That’s another good suggestion. The opening of Life of Pi is stunningly gorgeous cinematography.
IMAX Enhanced is a pseudo-format IMAX developed with several leading electronics manufacturers that purports to offer a superior experience when playing back IMAX Enhanced content on supported hardware.
According to this article, one of the main differences is that in IMAX Enhanced films the aspect ratio is 1.9:1 instead of the common 2.39:1 “scope” ratio. Although the article calls this a “huge chunk of screen real estate,” IMHO the difference is subtle and not very noticeable. The film was shot with the scope ratio in mind, so there isn’t likely to be much in that extra strip at the top and bottom that makes a difference.
IOW, it’s all just marketing BS.
One thing to keep in mind with this is viewing angles. Too close and you are turning your head or the edges are in your peripheral vision. Think of a cone drawn form your nose to each edge of the TV. IIRC the ideal angle is 30-40 degrees.
Also, people who mount their TV high (e.g. above the mantle) will have to look up at the TV to watch which is not great either.
I’m going to go the opposite way of everyone else’s suggestions of wide-open expanses and recommend something more claustrophobic, like The Descent. Turn off all the lights and you’re there in the cave with them.
While not claustrophobic (at all) I will add to “going the other way” on colorful movies to something like Ran by Akira Kurosawa (basically “King Lear” set in Japan). Amazing cinematography (and I guess it is colorful in its own way…a stark juxtaposition of color and bleakness).
A few more recent movies: Nope and Asteroid City. Not huge effects but the color palettes are subtle yet gorgeous. I bet Barbie would look great in hi-res.

Roger Ebert once described his ideal viewing angle. He said he liked to estimate the width of the screen and then sit that distance from the screen.
What you’re going to notice more than anything is modern TVs’ HDR (high dynamic range) capabilities. This basically describes the light/dark range that the TV can display- TVs with HDR 10.10+ or Dolby Vision or HLG are all competing HDR standards.
TVs with good HDR are spectacular looking, even with regular old 1080 content, relative to non HDR televisions.
That said, the Netflix “Sandman” show has some of the most stunning visuals I’ve run across since I got my new TV last year (55" LG C2).
A collection of 6 stories that are hit and miss, but the cinematography in The Ballad of Buster Scruggs is simply breathtaking on a large high definition set.

One thing to keep in mind before you upgrade other equipment to 4K (if you haven’t already) is viewing distance. You have to be really close to a 4K tv to notice the difference between 4K and HD.
Interesting, thanks. I’ve bought a 55" Samsung and I suppose I sit about 7’ to 9’ away from the screen.

What sort of soundbar did you get?
A Sony HT-G700, on the advice of the salesman, I really know little about these things.
Thanks for the recommendations everyone!
Not a movie, but I have to suggest the Planet Earth documentaries (two series). Visually stunning, and you have the subwoofer that you need for David Attenborough’s voice.

Happy birthday!
I wondered what that cake was about, thanks!

Good idea, I can watch some arctic-foxes in glorious high-definition
An interesting experiment for you might be Stephen King’s/Frank Darabont’s, “The Mist.” See how the mist looks on your TV and what disappears into it or comes slithering out of it. Then go inside the supermarket and see how the monsters hold up. The photography was fantastic – two cameramen with hand-helds were weaving in and out of the crowd and over/under each other and the result is very in your face which adds to the suspense. The few splashes of blood throughout will probably jump right out at you, seeing how much of the film is gray.
Or, you could just watch Darabont’s B&W “Drive-in movie” version and compare.
Let me know, please, I’m curious.
The Spider-Verse movies. Every frame is a work of art.
In a totally different direction, I found that the way my new TV enhanced black images made old black and white movies (like Dr. Strangelove) look fantastic. Color movies looked better also, but the black and white improvement was amazing.
Good idea. If the OP has not yet seen Raging Bull on a good screen this would be the time.
