You can take that 15 year old photo, scan it and upscale it to meter width and keep sharp edges and so on. Try doing this with that fancy iPhone picture.
An early-2000s consumer film camera, addressing roughly the same market as a modern iPhone camera, is not going to have nearly the lens quality, nor will the mass-market film stock have the grain resolution, nor will the 1-hour photo print have the transfer sharpness to survive a scan enlargement to a 1-meter-wide print. The result will look grainy and blurry compared to an enlargement from a recent iPhone.
An early-2000s 35mm SLR with professional film and a high-end darkroom print will look great enlarged, but then an iPhone is no longer an appropriate point of comparison.
