I have had the Ub900, the Oppo 203, and the ub820.
If you are just needing HDR output and aren't looking for the player to do any tone mapping (whether to SDR or HDR at a different target Nits) The oppo is a great player. And if you need multiform playback, it's probably the most comprehensive player out there. Build Quality is top notch.
But if you need tone mapping, the 820 is far superior. I don't think oppo will ever fix theirs, and since Panasonic had it right with the ub900, they have demonstrated they understand tone mapping far better than oppo does. The 820 just takes it to another level. Even with the ub900 I could get very good SDR BT2020 and adjust the dynamic range slider a bit to brighten up the overall image but at the cost of some washout and clipping of whites. Now with the black and white tone curve settings, I can adjust the dynamic range adjustment to +5/6 and then dial the black tone control to -3/4 and eliminate the wash out without clipping black detail. I can then adjust the white tone curve control to +2/4 to smooth out the highlights to minimize clipping and smooth out gradients to eliminate the occasional blown out details....particularly on faces.
For me it is a game changer. With an older JVC 4910, which can accept a 4k signal and shift it and does about 85% P3 with BT2020 color profile installed, I am able to watch my collection of UHD discs for the first time and not feel like the blu ray version looked better. It only took close to 2 years, but finally! I still need a Integral to handle the HDCP/HDMI version handshake, but that's no big deal.
I don't really care about apps on a player, but for UHD playback and tone mapping, right now there is nothing better than the 820....not even close.
