UCECLeft-Angled Micro HDMI to HDMI Male Cable Stretched Length for Cameras

will this work for displaying 4K resolution?

Does it support 10 bit full 4k output from a panasonic gh4 to an atomos ninja flame or am i stuck buying chinese cords from atomos for 4x the price?

Does this work on Sony A7iii?

will this fit a gopro? Gopro has a micro hdmi but the plastic around the connector looks like it might be a little too bulky to fit
