I have been stewing over how to ask this question for the past 3 days.
This thread, and the "original" thread by Dave H, are primarily about setting up the technical side of LLDV using our HDFury devices, but very little has been written about what it looks like.
My comments relate to my system which comprises an Oppo 203--> Vertex 1--> JVC RS500 ( with a Arve custom curve).
After the initial teething stages of getting everything set up correctly in the hardware ( Mark's custom EDID, importing Dominic's LLDV colour profile, configuring the JVC Macro) I have tried to do some comparisons.
UHD discs I own that are DV discs include " Knives Out" , "1917", "First Man", "Wonder Woman".
Your comment in your review seemed to sum things up rather well for me:
" Comparing the "regular" HDR10 image to the Dolby Vision one was not instantaneous by any stretch, but I watched various scenes from both versions back-to-back and found them equally appealing. "
Obviously, switching between "modes" makes things very difficult because changing from DV to HDR10 can take a couple of minutes by the time all the setting changes and re-syncs occur using a projector system.
My question is really: Are people genuinely able to see a discernible difference between Dolby Vision and HDR10 using a projector system capable of 100nits?
To me Dolby Vision looks EXACTLY the same as HDR10.
The supposed improvements ( 12bit vs 10 bit colour, less posterisation) are impossible to pick when it takes a couple of minutes to swap between formats.
And as for converting HDR10 to LLDV, well, again I can see no difference.
Do people think they could tell which was which in a blind test? How can people claim this is a "game changer"?
I think I reached the limit of my "law of diminishing returns" in 2017.
