Thanks again for the clarifications.
It was more for curiosity purposes - but obviously expecting not - on the Sabrina front, mostly in case of the possibility of it having been on there in an upscaled format. I do actually have Sabrina The Teenage Witch on DVD anyway (as well as Boy Meets World).
I'll most likely subscribe to Disney+ at some point anyway (for the 7-day trial at the very least), but it would have been nice for everything I remembered to be on there. As usual it's likely another thing that's down to rights, but hopefully some things will end up on it at a later point.
I do agree with Hoonigan about licensing restrictions like all of this being wrong given the global reach available in 2020 though.
