"The Lion King", "The Little Mermaid", "Beauty & the Beast", "The Hunchback of Notre Dame", "Pocahontas", "Mulan", & etc. Direct to Home Video sequels got Blu-ray releases.
If those other Disney movies' Direct to Home Video sequels (most of them, I've never seen) got Blu-ray releases, best believe "Aladdin & the King of Thieves" (& even "Return of Jafar") deserve a Blu-ray release.
And most of those sequels are early to mid 2000s and came out straight to blu tho. They weren't re-releases
Movies regularly being released on Blu-ray wasn't a thing till the late 2000's. All the movies I listed DTV sequels got their Blu-ray releases at the same time their original movie was released on Blu-ray. So none of them were Direct to Blu-ray.
