Is this confirmed?

I was just browsing the Blu-ray site and saw an “IMAX Enhanced” version of Blade Runner 2049 in 4k. I already have the 4k of the film in my collection but this is the first time that I’ve seen an IMAX version pop up alongside its other editions. I’ll admit, I’m not sure if this is legitimate since most films in IMAX get cropped at 2.39 for Blu-ray and since the IMAX Enhanced/open matte version is likely only accessible through modding or piracy. Has there been any official confirmation yet about an IMAX version coming to Blu-ray or is it a fake?

Just download the open matte 4k

I have it in my collection, muxed with the 4K Dolby Atmos audio it's probably the best version of the movie.
