I would argue it depends on the person. I'd love to be able to test this independently myself, but I don't have enough cash to spare to do so.
If you're aware of folks testing this, it'd be great to share that. The fact remains that 4k displays have been available for non-AMD laptops for a very long time (at least a few years) so they keep making them and people keep buying them, so I'd like that arrangement to be offered at least for AMD laptops as well, because it's definitely something lots of people, as this thread clearly demonstrates.
