I can't see any change in picture in L2_trim_chroma_weight, L2_ms_weight, nor any L3 and L8 tests.
Please, can you explain to me what this means? It suposses any problem to Dolby Vision FEL/MEL processing on this device?
This is expected and it means the CCwGTV (or your TV, but unlikely as you said it's the same in player-led mode) only supports CM v2.9 Dolby Vision.

the Zidoo Z9X will only resolve black levels down to 85. The Nvidia Shield has been tested and it correctly resolves all the way down to 64, as does my LG C9 internal player. It would be interesting to see which devices pass the test and which ones don't.
That pattern isn't free but we've had it for a while and it just shows some issues with HDMI input devices.
I thought the Shield also had the issue, though.
The FireTV Stick 4K (2018 and 2021) clips at 72 on LG C8-C2, assuming your pattern is the same as what we've had.
You can try the same pattern but with modified metadata from RESET_9999's test files: black.levels.pattern.modified_3079.ts
If that improves the black clipping, then it's the same issue.
