Didn’t see this mentioned lately, but Amazon Prime’s remastered version of The Cloud Minders presents the remastered effects in 16X9 widescreen. However, it’s very jarring with the majority of the episode still in 4X3, including with overlays of the new effects. This appears to be the only episode presented in this format. The rest appear to all be in 4X3, as the remastered Cloud Minders is on Netflix.
