USB-C to HDMI 2.0 adapter that do not support HDR10 pass-thru:

Anker Do not support HDR10 pass-thru. No plans to add the support.
Club3D Do not support HDR10 pass-thru. Working on firmware update to add support, but ran into technical difficulties, so no HDR support for the near future.

I am still searching for an adapter that does. Looking into Cable Matters and UpTab. The UpTab one is interesting, as the MFR claims HDMI2.0a while no other MFRs claim the "a". (HDMI2.0a was created to support HDR10, while b for DV) I am not sure this is what was intended, or the MFR just failed to recognize the "a" is for HDR10. The chip is Parade PS176, which was also used in Club3D adapter. I have yet seen users mentioning about HDR10 support anywhere.

I'm too interested in those adapters because my HTPC mainboard has DP1.2 port which enables 4k@60Hz. It's not clear to me if the issue of HDMI 2.0 adapter that do not support HDR10 pass-thru relates to bandwidth limits, or the conversion chip or something else. And there may be a typo with "a" or "b" following HDMI2.0 sometime as well.

It is the LSPCON chip inside that does not properly pass thru the HDR10 meta data. Maybe a firmware update will fix it, or maybe not. All Intel Graphic will have the same issue as they need a LSPCON chip no matter it is desktop or laptop since Kaby Lake processor does not support native HDMI2.0 (a or b). At least on the desktop you can get a discrete HDMI2.0 graphic card to avoid the LSPCON issue.
