Well yes but I cant say that out loud since this is an AV1 section.

Google's Tensor G3 SoC is rumored to support AV1 encode at up to 4K at 30fps.

We'll find out soon enough.

Amazon Fire TV Stick 4K (2nd generation) was announced today, it supports AV1 decoding. It is out on October 18th in uk, not sure about other countries.

Dolby recently re-added AV1 profiles in their public spec, so it's not dead yet.

Also, I've received my new FireTV Stick 4K Max 2nd gen (2023) and it still has no FGS with AV1 in Dolby Vision mode.
Still works fine in HDR10.

DoVi Profile 5 takes a lot more compute/pixel than HDR-10; max fps has typically been half (still better than dual-layer). It wouldn't be entirely surprising if there wasn't enough GPU compute left for FGS.

Just speculation on my part; I have now direct knowledge. There haven't been AV1 DoVi test streams, so it just may have never been turned on in SoC OEM drivers. The default is to no turn on features you can't test, for obvious reasons.

I would assume it probably has more to do with missing AV1 Dolby Vision streams, but if vendors could implement it I assume they had access to some.
Or maybe just regular non-FGS streams, I don't know.

Anyways, it might take a while for it to be fixed since nobody is distributing it.

Film Grain Synthesis works in FireTV Max V1. I have tested this in Kodi with different video files.

Yes, I know.
I'm talking specifically about AV1 Dolby Vision videos, FGS doesn't work with those only.

Is there a video online which I could test?

Sure, here's one: https://0x0.st/HWpI.mp4

Thx. Indeed no grain. But it works with Chromecast 4K [the white stick](not 100% realtime playback)
