Same thing for the ps2, it was one if not the cheaper dvd player on thise days.
DVD actually made a difference on almost every single set though. UHD blu-ray really only matters if you a 4K HDR set, and a half-way decent one at that. Decent 4K HDR sets aren't super expensive anymore, but the adoption rate is still slow. UHD blu-ray is never going to matter for the market. Streaming is good enough for most people.
