I intend to play the movie on LG OLED 65".
I admit I'm not familiar with most of the technical data above.
Could someone advise me which of those two alternatives might give me a better picture? (whatever "better" means...)
Thank you

The first is HDR while the second appears not to be.
That could be an issue; I don't think HDR has all it's kinks worked out due to lack of standards.
My TV has basic HDR10; sometimes it burns your eyes out - like looking at the sun.
The literature talks about "speculative highlights" and "deep shadows" but reality is
miles away from this -
The AVC video probably has a little more detail detail. The first video is HDR and should have more dynamic range if you're set up to play HDR properly. It's up to you which looks better.

It's against forum rules to discuss pirated material. Ask where you got it from.
