Data Blocks

Hi I would like to have more information on data blocks.

For example, what happens if I enable DCI-P3 and what are the Metadata MD0, MD1, etc.

Also:
- What is Quantization: Selectable RGB range and YCC range?
- What does the Transfer functions of the HDR section do?
- Is it safe to add those blocks and can I remove them later?

I upgraded my laptop screen to a better true 8 bit, wide gamut (100% sRGB, 90% Adobe RGB and 90% DCI-P3) and I want to take the most advantage of this screen's colors and bit depth.

Thank you
