Infuse will only play Dolby vision profile 5 which is what is used by streaming services. Unfortunately this is the only version that Apple supports. It’s not an infuse limitation. UHD discs are profile 7 and not supported. I’m that case you will just get HDR.
The only way to get a true conversion is using the master file and Dolby’s tools. Taking a disc copy that’s been configured to a specific setting and trying to convert it to another profile won’t end up with the same result. You might be able to make it do it but it won’t be the same. It’s akin to editing jpeg vs raw
What’s the point of Profiles in DV? Is it to artificially segregate the technology to sell new stuff? It’s already complicated like that, is this driven by a real added value or it is just a marketing stunt?
I tried to read the link but it’s very difficult to understand.
