In LLDV player led Dolby Vision, I see no differences between HDR10 and Dolby Vision test clips

[AvailableMovie]

Hello.

1. I'm looking at different test clips such as "Terminator Dark Fate HDR10," "Terminator Dark Fate Dolby Vision," "Atomic Blonde HDR10," "Atomic Blonde Dolby Vision," and I see no differences between them.
   There's also a compilation video of shots from Ballerina, and it's showing different Dolby Vision layers, but I see no changes.

Particularly for the Terminator Dark Fate clips, the lightning/electricity does not seem to be brighter in any of the clips. It's supposed to be brighter in the Dolby Vision clip.

In Settings > Coreelec, I tried max luminance at 1000 nits, 1400 nits, 1600 nits, and 2000 nits.
In Samsung S90F tv's settings, Peak Brightness is set to High.

This link has the Terminator Dark Fate clips. Sorry I can't find where I downloaded the compilation video of Ballerina shots.

2. Three Dolby Vision test files work correctly on my setup ("THIS DEVICE CAN DECODE FEL", "woman at 80 seconds in", "white credits text during the Power Rangers end credits").

3. I'm doing LLDV Player Led Dolby Vision. Equipment: Ugoos AM6B Plus, new install image Coreelec Avdvplus Release 9, Samsung S90F 77 inch QD-OLED TV.

Thanks for reading. It's amazing to play certain DV test clips in Coreelec that look correct, whereas before playing off of PC I didn't get the correct results.

With my versions of these videos I can see the difference so not sure what is the problem.
