Trakin Tech has posted the overview of the Realme Sled TV and he has got a defective unit, he tells at 1:27....lol and they want us to buy this even when their TV's first review unit is a defective one
Yep both are HDR formats. But each format needs it own render, so if Dolby Vision is not der it will render in HDR10/HDR (which ever is available on TV) , same for HDR10+.
Netflix, Disney+ Hotstar supports Dolby Vision
Amazon Prime Video supports HDR10+ for now.
Dolby Vision needs to be procured where as HDR10+ is freely available.
