Young Royals 2021

Sorry there is no wrong with your dv file.
✓After doing 3 hr research on Dolby vision I found this things:
✓There are 2 different layer of Dolby vision layer5 and layer 7.
✓Layer 5 are the MP4 file.( only support Dolby vision or only HDR)
Layer 7 are in mkv formart.( support both Dolby vision+ hdr) L7 are recent year technology.
All tv support layer 5 Dolby vision and can decide L5 only .They can Play L7 file i.e mkv DV but this need an external player such as shield pro which is too expensive for Indian user in order to play only L7 file.
All streaming app play only L5 dv file except Netflix . Netflix Support L7 dv but with what techniques thts secret !
✓I hv all Dolby vision movie with MP4 format .
