What is the native colour space of SDR 2160p movies? BT.709 or DCI-P3/BT.2020?

Why not? Wouldn't UHDTV displays that conform to Rec.2020 expect the content to be in BT.2020 when the definition is 2160p SDR (Edit: https://en.wikipedia.org/wiki/Rec._2...em_colorimetry), just like HD displays expected BT.709 when being fed > 576p? Maybe the Radeon is enforcing the standard really hard? (Edit: i.e. indicating BT.2020 in the HDMI metadata when it's outputting 2160p even though madVR is sending BT.709?)
Just like 8-bit HDR or even 8-bit UHD, maybe BT.709 UHD is technically accepted by some displays but not following the standard and therefore not tested/considered by manufacturers?
