I can encode and provide clips of Rogue One sequences in 4K if anyone needs. Either in native HDR, or “SDR conformed” in 4K native if needed. I used the entire film for my own 4K HDR Rogue One/ANH edit.
If someone can provide me a timestamp, I’d be happy to upload a clip.

4K HDR Native (Note: Windows sucks at taking native 4K HDR screencaps. The above “conformed” shot is closer to how the colors should look, while the detail in this image is more accurate)
