Toei's style of "remastering" is nothing short of a disaster.
They didn't color correct Sailor Moon or Dragon Ball when they "remastered" them for DVD.
When they released Galaxy Express 999 on BD, it was an upscale done by the infamous Q-TEC.
As for Funimation, they did a bang-up job with the first 34 eps of DBZ and then burned out so they just decided to cut the top and bottom off and crank up the DEEN. The most recent releases look like abject hell, but they can clearly do good work when they try.
We need to find as many 16 and 35 mm elements as may be floating around, it might be our only hope...
