Because your statement was - at best - misleading.

I too have read that Kalemsoft can play many (certainly not all) video codecs at resolutions up to 1080p. Proper playback depends not just on codec support, but also that a video's bitrate is low enough. I can encode a 1080p video with a low enough bitrate to play on decade old machines, or high enough to stall on modern desktops.
There are other benefits found in hardware supported video.
Firstly, dedicated hardware will typically be able to play videos at higher resolutions and at higher bitrates.
Secondly, hardware video playback typically requires fewer system resources and thus can play a video while using far less battery.
These are not inconsequential benefits.
