The demographic buying UHD Blu-rays are film enthusiasts first-and-foremost, at least at this point in its lifecycle, and most likely upwards of 30 years of age given how the average cost of a single UHD Blu-ray is around $40, so folks who grew up with the OOT. I don’t think a 4k SE would be met with much enthusiasm at this point. At least this is my assumption.
Especially since 40% of it, because of the CGI, would be uprezzed.
