Apparently Disney just updated TROS on D+ with a completely different color correction with less blue. No idea why they did that but it’s kinda funny.
Sure, it might be worthwhile to compare the new Disney+ version to the LUTs by skenera; but Bluray is going to be a higher-quality source than a web rip. So (assuming that Ascendant was based originally on the Bluray) I’m inclined to just stick with what we have here and ignore the new version.
