It's been going around that the last Roku update or version I guess you could call it messed up the Dolby Vision on TCL Tvs. I have the TCL S517 and whenever I play a Dolby Vision movie the screen changes from dark to light and light to dark in all scenes of the movie it's not supposedto do that. TCL is aware of the problem. Is Roku going to fix this issue? Anyone else seeing it? Thx
I'm also having a Dolby Vision issue, but I'm not sure it's this one. Mine is that it doesn't look right--grayish letterbox bars, lack of contrast, deep blacks. It only applies to signals coming externally--Netflix and Dolby app look as they should on the internal apps.
Setup: LG BD player/Apple TV 4K > Yamaha 3070 > TCL 65R615.
