The UHD disc format, still Blu-ray disc but different 0 and 1, uses HEVC/H.265 for the video codec and uses a better compression algorithm. AVC is H.264 and is widely used on Blu-ray disc amongst other digital formats.
The Blu-ray disc released by WB for Stephen King’s IT (1990) uses the AVC codec. As obviously stated in this thread it’s the edited 187 minute version compared to unedited sans commercials as was broadcast.

Well the PS4 plays Blu-Rays, but idk about HEVC. I would imagine so.
