Die Oberklasse

These days I'm experimenting with a Nvidia Shield 2017 connected on my Loewe One55 (built in 2017). Works pretty fine, but I've a question about the colour space.

Setting up the Nvidia Shield HDMI setting on 4:2:0 10 bit rec 2020 gives me a good HDR picture while playing back a HDR source. "Utra HD HDR10" is also displayed in the tv's infobar. This is possible using Kodi or Netflix.

When I'm playing back a "normal" full HD movie with the above HDMI settings, I get a weak picture, with poor colours. Setting up the shield in a 8-bit rec 709 setting, gives bright vivant colours. So just playing with the settings before I watch a concerning movie to get a good picture...

My questions:
1. I can't find any info about the used screen in my Loewe One 55. Is it possible that I don't have a "real" 10 bit HDR panel wich results in the poor colours in 10 bit rec 2020?
2. At the end of this year, I'm planning to buy a 65" OLED tv and the one 55 moves to my sleeping room. The bild 5.65 OLED is my all time favourite. Does somebody knows the results of playing back a normal full HD movie using the Shield setted up on 4:2:0 10 bit rec 2020?

Thanks a lot for the advice.

(Answer in German if you like... And maybe I have to write in. Could improve my knowledge of that language , but I think you guys will laugh reading my German )

Question 2 = solved, no issues with OLED's at all

My colours with "real" HDR are good. It's just when I use the HDMI 10 bit settings combined with SDR pictures, the colours are weak. 8 bit setting with SDR picture is fantastic. That's also a software bug? Or am I wrong? At least that's what I understand from SoundAuthority's story.

(does somebody know the used panel in the One55? 8 bit or 10 bit?)

10BIT (8BIT + FRC)
