Disney Plus Has Finally Launched a PS5 App With 4K HDR Support - IGN - IGN

As noted by The Verge, PS5's former version of the Disney+ app was actually a PS4 app that was running on the newer console, which meant visuals were capped at 1080p resolution, whereas the relaunched Disney+ app has been designed natively for PS5 and now supports 4K High-Dynamic Range playback across the service's growing catalogue of titles.

"A key part of our global expansion strategy is to meet consumers wherever they are, which is why we're excited to enhance Disney+ for PlayStation 5 users," Jerrell Jimerson, EVP of Product and Design for Disney Streaming, said in a press release.

"The ability to support 4K HDR video streaming on the platform will also improve the viewing experience for fans.".
