Hard to say with Samsung being so opaque when it comes to firmware updates.
Basing it on this response from Samsung saying they were going to fix the problem when it was never their problem to fix in the first place. It was a problem with the Switch itself affecting multiple TV manufacturers, which I believe Nintendo themselves fixed in a recent firmware update.
You should just be able to toggle whether or not an HDMI port auto switches, IMO.
My bad. I thought you were talking about the hdr toast
