The Philips does the same, but its color mapping has been found to be a little off. So, the Panny is remapping, it is a very good image with just HDR stripped because I had one. I sold that setup when the 203 looked like it would have it.
When playing HDR content you have several choices of output:
1) Auto -- sends BT2020 w/ HDR metadata so long as the TV says it can accept that. If not, works like OFF below.
2) ON -- sends the above even if the TV says it CAN'T accept that (so long as HDMI copy protection is satisfied)
3) OFF -- sends BT709 for output Resolutions 720p or higher, and BT601 for output Resolutions below 720p, with HDR converted to SDR in the player. Use this, along with downscaling from 4K content to 1080p output, for playing UHD discs on legacy 1080p displays. AUTO should give the same result to such display, but OFF forces this result if need be.
4) Strip Metadata ("experimental feature") -- Sends BT2020 without HDR metadata. What's not clear to me yet is whether the player is also doing *CORRECT* conversion of the HDR content to SDR as part of this (i.e., using the metadata to do that before the metadata is stripped). Expect this feature to evolve as OPPO gets more feedback.
