Usage of GLK-U2CX

I want to use the GLK-U2CX as a HTPC and as a remote PC I can log into via a remote desktop session in a vacation house.

To make sure I have the right expectations I have the following questions:

1. Will the GLK-U2CX be able to support the best possible audio and video formats that are used at the moment? For me that would be translated into full support for Dolby Atmos (i.e. to work in combination with my Samsung HW-N950 soundbar) and Dolby Vision (i.e. the LG OLED C8 series, and note Dolby Vision supports 12-bit color). Is this supported in the hardware and software (Windows 10 Pro) of the GLK-U2CX;
2. Can you put the GLK-U2CX into hibernate mode and get it out of hibernation with the Gyro remote and if hibernated wake it up again via Wake on Lan?
3. I have read about the heath pipe solution and that looks good to me, but what is the expectation as to actual noise levels when you watch movies? I expect not to have a distortion by the noise of the GLK-U2CX when I watch a movie with the highest audio and video quality. Is this a right expectation?;
4. In the technical description I have read the following: a. RAM: 4 GB DDR4-2400MT/s (Pre-installed), 8GB Max. supported and b. Memory Slot: 2 x DDR4 SODIMM-sleuf, ondersteuning voor twee kanalen (elke kanaal ondersteuning tot 8 GB) -> is the max supported size 8Gb (2 x 4Gb) or 16 Gb (2 x 8Gb)?;
5. In the technical description the following is mentioned: Storage Expansion: 1 x 2260/2280 SATA M.2 SSD, but NVMe M.2 SSD is NOT supported. What does this mean as to support for modern and fast SSD's like the Samsung 970 EVO in real practice?
6. Ideally, I would like to use the GLK-U2CX with a USB-C hub that supports Power Delivery and then I feed the PC or USB-C hub via a decent power supply that powers the PC and all devices I attach to it. I understand that the GLK-U2CX supports this set-up, but I did not see a proper USB-C charger that can be plugged into the wall outlet, maybe this can be explained a bit more in depth? I also saw that only port 1 of the two USB-C ports supports PD. I am figuring out how to feed power into the GLK-U2CX via USB-C PD and at the same time being able to use it further in the distribution chain as well (for a PC monitor for example that is fed with one single cable (so including power) via USB-C). Being able to supply power via USB-C PD is a big plus for me that helps to get rid of brand specific power supplies with different plugs and voltages etc. Hope this feature can be explained a bit more.

I hope this forum is the right place to discuss the above questions and maybe follow up questions. If not please let me know.
