Upscaling Algorithm for pi 5

Hi, now that the pi 5 has so much more horse power and all the non-h265 content is decoded by cpu, would it be possible to add a better upscaling algorithm like lanczos 3 optimized? It makes a big impact on older DVD quality or lower content. This is especially useful with non standard resolutions, which a lot of the older content is, that can't be whitelisted.

Thanks
