Hello, new here and in the TV box world. I have been reading for the last couple of days this forum and the LibreELEC one but I need a last confirmation.
I have an old TV right now but I want to buy something that I can use whenever I decide to upgrade it.

What I want:
Kodi capable device that can play high bitrate BluRay rips over a local network (so 5Ghz + gigabit ethernet)
4k resolution (so I guess HEVC support)
HDR10 support (maybe HDR10+ and/or DV if possible)
5.1 audio (DTS:X and atmos?) passthrough so I can connect the device to an AVR

I do not mind having to configure things myself (= not need for just plug & play).

I think that is basically it... reading the stickies it seems that my best option is a TV box with AMLOGIC S912 chipset and installing LibreELEC.
Reading the LibreELEC forum it seems that the ones with S905X2 are better, but the "4K HDR" sticky here says "New S905X2/Y2 chipsets will have No LibreELEC / CoreELEC Kodi support. Kodi HD audio is likely broken as well."

So I guess I should go for a S912 device, right?

I do not think I'm missing anything right now. In my country this kind of stuff cost between two and three times their price sometimes so I am trying to spend the least amount of money possible (lets say U$D60 original price if possible).
In that range I found the H90pro+, some MECOOL ones, and some Tanix ones.

Is it the S912 the best one for my needs? If so, what device should I buy?

Sorry for the long post and thanks in advance.
