Are there limitations to the LLDV decoder, regarding BL, Profile, L2 trim?
Are 2020/P3 colorspace , PQ and max luminance the only required parameters for the HDR10 layer, what about maxFALL and maxCLL? Does a tv customise its tone-mapping based on those aswell?
Does the LLDV player decode to the specified luminance range from the spoofed EDID?
Are there limitations to the LLDV decoder, regarding BL, Profile, L2 trim? I am sure there are, but I am not sure what they are. For example, some discussion of the target nits suggests that telling a DV decoder anything lower than 100nits as the display capability doesn't work right (or, at least, defaults up to 100nits). There is likely a lot to be learned by asking your question here: https://www.avsforum.com/threads/dolby-vision-including-hdr10-conversion-w-dtm-on-projectors.3097934/
Are 2020/P3 colorspace , PQ and max luminance the only required parameters for the HDR10 layer, what about maxFALL and maxCLL? I am not sure because I did not go down the path of rolling my own EDID. I simply used one that had the key parameters I wanted. This thread has a detailed discussion of creating EDID's from scratch: https://www.avsforum.com/threads/alternative-devices-for-enabling-lldv-please-read-posts-1-2.3254266/
Does a tv customise its tone-mapping based on those aswell? Some TV's try to honor the meta data they see like maxFALL or maxCLL, from what I have read. And some TV's ignore it completely. And some content has erroneous data for one or more of those values sometimes, which lends some credibility to the idea that ignoring that meta data may be smart for HDR10 content. So, I infer that the literal answer to your question is that "it depends."
Does the LLDV player decode to the specified luminance range from the spoofed EDID? This is my understanding, yes, and the main value of the process.

Thanks for the write-up.
