Correct cable spec for AppleTV 4K (Dolby Vision) to LG OLED (Dolby Vision) @ 4:4:4?

Super new at all this, and have no idea how to do the math. Any help will be super appreciated.

The TV is LG B7A, and AppleTV is the 4K one.

Will this cable work for 4K Dolby Vision @ 60 Hz @ 4:4:4 chroma mode (and whatever else max spec that the two devices support)? https://www.amazon.com/HDMI-Cable-6f...dp/B00NQ9OQU2/

Thanks!

Forget the Math, forget the numbers and keep it simple - look for a cable carrying the official 'Premium HDMI' certification/Logo and ignore everything else.

PS I am assuming you are looking for a 2m (6') cable

Thank you! Yes, I'm looking for a 3' or 6' cable. I was concerned after reading comments on Reddit where people couldn't harness the "full power" of the TV and AppleTV (HDR10 and 4:4:4 at the same time for instance) without the right cables. Thanks for that link. Since the one I linked to doesn't have that certification, I'll keep looking!

This should work? https://www.amazon.com/Monoprice-Cer...dp/B01GCGKI3O/

PS. Since they are similarly priced, would I lose anything (picture quality, errors, etc) by getting the 10 ft one instead of the 6 ft one even though right now I only need about 2-3 ft?

^^^^ if you read the description it indicates that the cables have been certified by an ATC (Authorized Testing Center) which is the HDMI.org approved certification program. Keep in mind that no cable is 100% guaranteed to work in every system. A lot depends on length (even tho there should be no problems at 6'), bend radius, HDMI hardware chipsets on source and sink, etc. All you can do is try.

Thank you for letting me know ATC is indeed the approved certification program. I meant to ask if there will be a difference between 6' and 10' cables. I think I will go with the 10' (even though I only need about 2' now) unless I hear from you otherwise. Thanks!

8m (26') is where the 'fun' tends to start once you go up to UHD bandwidth - you should be fine at 10' with a Premium Certified cable.
