Yes, but I assume that the streams are visible. I know from a reliable source that Amazon offers 1080p with DV/HDR. Likewise Disney+.
The question is whether it needs other keys for that, or whether the current ones are enough. :)

Disney+ uses different KID for stream types, in this case all HDR versions share the same key as the 4K resolution. So HDR would at this moment not become availeble in SF as long as the do not get a Special L1 key or support Playready and get an SL3000 key.
