If I remember correctly Adywan did consider doing it and did some testing but it was too much work for something that ultimatly looked worse than no glow.
Really I’m surprised because a fan did the glow for the prequels lightsabers on YouTube and it looked great.
This video?
The ambient glow only works when the subject is fully lit, like in that video. Try doing it during the carbon chamber duel and it is impossible unless you recreate each character using CG & 100% match their moves because there is no visual information on Vader (especially his helmet) for the most part & other areas of each character. I did many test and decided it’s just not worth all the work, especially when so many shots would be impossible to convincingly add any ambient glow.
And there will be no HDR/ Dolby Vision colour grade. I see people ask this a lot, along with asking for a Dolby Atmos sound mix. I’m just a guy working on a home PC and not in a fully equipped professional studio. I just don;t have the facilities to be able to do things like this.
