Was that an actual color regrade though? It kind of just looks like the saturation has been bumped up a notch.

Pretty much every change in ROTJ is complete rubbish however.
Funnily enough I quite like the Hayden change though. Yeah it’s unnecessary, but at least there’s a reason behind it (the validity can be argued).
But Jedi Rocks? CGI Sarlacc? CGI R2D2? Vader’s “Noooo”? Jabba’s Palace door size and then shrinkage? What were the point of these?

I think the ESB SE ('97) is a tad better than the theatrical though, minus some wonky CGI.
