To whom it may concern: the new version is out - Alien: Covenant IMAX [Fundamental Collection] - now all the IMAX/open matte shots are perfect, no more subtitles and/or logo remains, and eventual top/bottom “slices” differences in brightness and/or color, due to the use of two sources, are completely gone.
More, it’s the usual multi language edition (English, French, German, Italian, Spanish audio and subtitles) plus the Russian tracks, and the English commentary with related foreign subs.
Now you can find it in that demonic place. Have fun!
