But isn’t AV1 just better than h.265 now regardless of the patents? The only downside is limited compatibility.

HW support for av1 is still behind h265. There's a lot of 5-10 year old hw that can play h265 but not av1. Second, there is also a split bw Dovi and HDR(+). Is av1 + Dovi a thing? Blu rays are obviously h265. Overall, h265 is the common denominator for all UHD content.

Most new UHD, yes, but otherwise BRD primarily use h264/avc
Encoding my 40TB library to AV1 with software encoding without losing quality would take more then a year of not multiple years, consume lots of power while doing this, to save a little bit of storage. Granted, after a year of non stop encoding I would save a few TB of space. But it think it is cheaper to buy a new 20TB hard drive than the electricity used for the encoding.
I avoid av1 downloads when possible because I don’t want to have to figure out how to disable film grain synthesis and then deal with whatever damage that causes to apparent quality on a video that was encoded with it in mind. Like I just don’t want any encoding that supports that, if I can stay away from it.
In MPV it's just "F1 vf toggle format:film-grain=no" in the input config. And I prefer AV1 because of this, almost everything looks better without that noise.
You can also include "vf=format:film-grain=no" in the config itself to start with no film grain by default.
I watch almost everything in Infuse on Apple TV or in my browser, though.
What's wrong with film grain synthesis? Most film grain in modern films is "fake" anyway (The modern VFX pipeline first removes grain, then adds effects, and lastly re-adds fake grain), so instead of forcing the codec to try to compress lots of noise (and end up blurring lots of it away), we can just have the codec encode the noisless version and put the noise on after.
I watch a lot of stuff from the first 110ish years of cinema. For the most recent 25, and especially 15… yeah I dunno, maybe, but easier to just avoid it.
I do sometimes end up with av1 for streaming-only stuff, but most of that looks like shit anyway, so some (more) digital smudging isn’t going to make it much worse.

With HEVC you just don't have the option to disable film grain because it's burned into the video stream.
I’m not looking to disable film grain, if it’s part of the source.
