Is this compatible for HDR?

Yes. These are compatible for throughput up to 8K with HDR.

It says it supports arc, but does not mention earc. does it support earc?

Use a PC monitor in 8k HDMI 2.1 in IMAX mode if the audio and video outputs properly then it's earc. Most games are good for testing for this feature as consoles don't have the ability to Id this need yet or smart TVs information section in the android tv settings menu. Also try a wireless HDMI connector to see if it's earc capable as the electric needs are more than standard HDMI cables for high bandwidth high speed internet 4k cable tv content streaming at active 10-bit video quality from such cameras in the near future as they want to start phasing out the eithernwt wire for HDMI cables also using eithernet soon here like with tb4 usbc only for power plugs and data cables for server workstation needs during the chip shortage retooling transition as well hey get rid of excess I/o ports are on mobos for a simplified consolidated manufacturing process soon.

Does this work with 4k 60hz?

yes, 4K up to 144hz or 8K up to 60hz

Is this 8k @ 120hz, 2.1 uhd dolby vision & atmos capable with earc?? and if not what is the return policy? bcuz nothing less is acceptable to properly

These do 8K @ 60Hz with Dolby Vision, or do 4K @ 120Hz and VRR, but depending on the TV you can't really do both. Sony X85J in particular will only do 4K @ 60Hz with Dolby Vision or 4K @ 120 Hz with VRR(though advanced Dolby Vision Game Mode may be coming to many new TVs).
