Does the OPPO 203 convert a Dolby Vision layer to HDR for displays that do not support DV?
that's because it's from a DV uhd bd (most probably should have .m2ts extension, but doesn't really matter for players).
first, you have two layers, one is a h265(hevc) HDR10 and the second one a h264/h265 DV enhancement layer, which is adding more information about dynamic contrast (for short).
this kind of material require a dual decoder; oppo has it, most tv's don't. lg, for example, has a single stream decoder, and could decode single stream DV (in this case, supplemental dynamic contrast data is embedded directly on main video stream, used if possible, discarded if not). this means tv's will not decode dual-stream DV material at all, mostly. oppo and other players will play main stream, though.
there isn't such a concept to "convert a DV layer to HDR10". actually, oppo will display 12bit output - more than 10bit in HDR10, and mostly will use DV enhancement layer to display DV on capable tv's, but only if you select "Dolby Vision" as HDR processing in oppo (i still don't believe this, considering it's only about a fake DV, but who really knows, out of Dolby Labs?)
in your case, that .ts file is displayed as HDR10, probably because you have selected "auto" in HDr processing; you could select "Dolby Vision" and seethe result.
