Hey it’s a bonus, what do they need to remaster anything for.
If for no other reason than because they likely won’t get around to even thinking about the OOT until the 4k UHD release and the GOUT is like 1/27 the resolution.
George got away with that on dvd because many people were still watching on their 4:3 sets and couldn’t tell the difference from a properly remastered disc, which of course would’ve been done in hd like the '04 master and at least be somewhat future proof.
Upconverting a laserdisc master of an entire movie trilogy all the way up to 4k just doesn’t sound like something anyone would do.
