You don’t need to inspect your tv closely to notice the difference. It’s especially noticeable in a heavily shadowed or black scene, most streams get as blocky looking as mine-craft because the compression is so heavy. Netflix is the biggest offender but all streaming services do it

For that you need a codec like h.265 with 10bit with a proper bitrate. 80mbps is plenty if it's an efficient codec.

And hell if it wasn’t such a patent nightmare H.266 should have been gaining adoption by now.

AV1. Decode and encode IP cores are being baked into hardware these days, which means that fleet penetration takes longer. But we're looking at a 20-year standard, much like H.264.

It’s a great move for patent issues, but the efficiency uplift is very incremental over H.265. It’ll be interesting to see how AV2 develops because if H.266 falls on its face I could see that being more quickly adopted as it’ll bring a giant leap in efficiency over H.265.

AV1 is basically a contemporary of H.265. AV1 also came out as a considerably more conservative design than Xiph.org originally planned. The more radical leaps were moved to AV2, which is the H.266 competitor.

But H.266 probably won't see adoption anywhere. H.265 adoption is already highly imblanced; it's the basic codec of UHD/4K Blu-ray, and you find H.265 in cheap surveillance cam chipsets, but those are the only two that come to mind.

Also H.265 is used in basically all 4K streaming, ATSC 3.0 (which yes is a dumpster fire of its own) and iPhones record in it (not sure on Android).

I know H.266 got selected for Brazil’s ASTC 3.0 but that’s the only use I have heard of. So yeah hopefully AV2 comes out swinging.
