Re: Roku Dolby Vision support in Matroska (MKV) containers
Roku rarely (well, never) answers questions like that and streaming one's personal collection is very, very low on their list of priorities. If none of the big boys (i.e., Netflix) is using it then they probably don't care at all. If streaming your own collection is your main focus then you'd be wise to look at other alternatives and avoid the frustrations that come with using a Roku device for that purpose.
