Film Preservation Society Blu-ray is a newer restoration than the previous Cohen one. From various review like Robert Harris and Damn Fool Crusade this new restoration is really good.

"a full frame 35 mm fine grain positive was scanned at 4K at an historically appropriate 21 frames per second. Following this, more than 160 hours of digital clean up was completed at 2K"

While it is included in Warner Bros 50th Anniversary Blu-ray it's still the same DVD version

Warner Bros 4K Blu-ray doesn't include this as an extra any more

The 2018 Kino Lorber Blu-ray and DVD releases as part of the "Pioneers: First Women Filmmakers" set are a newer restoration than the 2008 Kino Lorber DVD, additional info on Silent Era website, but it is worth noting the order of the movie sequences are not the same between the new and old releases. A couple comparisons uploaded to slowpics. The Library of Congress has a safety duplicate negative of this film, and it is also available for viewing on Wikipedia.

MoC Blu-ray slightly better than Paramount see DVDBeaver

Indicator Blu-ray minimally better than Kino Lorber Blu-ray http://www.dvdbeaver.com/film10/blu-ray_review_158/mae_west_in_hollywood_1932-1943_blu-ray.htm
