I would consider our South Cinema viewers unlucky as in Bollywood they have more production value and the technology was little ahead.
I feel jealous watching Hindi movie and songs in Ultra, Tips, T series. They have restored all the hit movies and the quality is fantastic, you can call it a near 1080p
Sometime back I remember watching a Song from Hindustani ( Indian) in YT at 4K. Trust me it was fantastic but with poor color grading but the pixel depth was good.
Indian is an Original Tamil movie and nobody bothered to restore it in the Tamil version.
