I put seven world one planet on yesterday 4K HDR UHD disc version on PS5. Holy crap that looks amazing. I ordered Blue Planet 2 4K HDR right after!
And now I ordered Perfect Planet as well, and Interstellar on 4K HDR (on sale atm) to see if movies can look great as well. It was filmed in IMAX, best chance of having an advantage of 4K, but more interested to see if HDR actually adds something to a movie. It does wonders for BBC Earth documentaries.
