I think that HDR / SDR is an exception, but to be honest, I'm not sure about that. You'd need to check with Crestron, or a Crestron dealer.
I ended up updating all my displays to be 4K capable displays because: (1) It is primarily cost driven - the cost to upgrade displays was cheaper than getting fancier NVX cards everywhere, and (2) Damn, if I have 4K, I'd like to be able to use it, even if just in the family room or master bedroom. Yes, my "fancy" room is the theater room, but it would still be nice to enjoy 4K elsewhere.
At times I only have content in 4K, depending on licensing (i.e. Disney - I don't like their Premere license agreement, so I never accepted that). And I'm still not thrilled about keeping two copies of movies (one BD/SD, the other 4K - it's cleaner to just have ONE copy of a movie). So Co-Star and just keeping 4K lets the "right thing" happen, regardless of the movie I pick, in my current configuration.
The problem with this approach: Most 4K TVs are large (that's what people buy). When I wanted a smaller TV for the Kitchen, that was tricky. But I did find one that was "small enough", so that solidified the approach I took.
In our case, the kitchen TV is an odd-ball (we'd be unlikely to watch a full length movie there). So the HDR/SDR thing never came up. When streaming, that's not really an issue (and streaming isn't really "HD" or "4K" anyway with the compression mechanisms). But regardless, the cost issue did come up, and it made sense to just get a new TV for the kitchen - the smallest we could find!
Hope this gives you food for thought and is useful, @MikeKobb.
