No, the PS4 cannot natively play PS3 game discs or digital PS3 titles—it lacks the necessary hardware architecture. Instead, the only way to play PS3 games on PS4 or PS5 is via Sony’s cloud-based streaming service, now part of the PlayStation Plus Premium tier (formerly PlayStation Now). This allows you to stream select PS3 titles, but you cannot download and play them locally like PS2 Classics. So, while you can access some PS3 games, it’s only through streaming—not traditional backward compatibility.
