Apple 4K streaming problem

[DaGodfadder]

Hi, I’ve got a strange problem.

I have an LG C9 and an Apple 4K box. Weirdly, whenever I stream 4K purchases or rentals from Apple they stream poorly (sometimes the quality isn’t even HD) - but when I switch over to Prime or Disney+ or Netflix, still on the Apple 4K box, the results are always perfect.

Last night I rented a 4K film from Apple for 99 cents (the weekly rental deal) and I was so aggravated by the terrible quality that I rented the same movie from Prime. The difference was obvious. Night and day. Prime was 4K whereas Apple was all over the place.

Sometimes I can get Apple purchases to stream in 4K, but typically the stream has major issues. It’s weird that Apple’s own box would work so well with other apps but not its own.

Any thoughts or suggestions?
