As with Deep Space Nine, Star Trek: Voyager is unlikely to ever get an official high-resolution remaster. The effects were shot on video rather than added to film after the fact, making it much harder to upgrade the quality than it was for The Next Generation. However, an unofficial project might get relatively close. Series fan Billy Reichard has started processing Voyager with a machine learning program that upgrades that '90s era image quality as much as possible. You won't forget that the show was made for tube TVs given the aspect ratio, but the AI is surprisingly effective -- it produces something you probably wouldn't mind watching on an idle afternoon if you're a Star Trek devotee.
