I am not aware of any laptops which yet come with 4/5k screens, so I presume this relates to desktop machines?
Gaming is not a consideration for me and the graphics incorporated into the CPU are reasonably powerful these days, so I would expect some benefit for Lightroom and Photoshop performance.
Scaling is OK in Windows 8 but it's not perfect yet and most noticeable on 4k screens. As you say it's third party apps that suffer the most although photoshop and lightroom are fine.
You can definitely get 3/4k screens on laptops, that's what I have currently. This is a link to the singapore site but shows the types of screens available on the OEM clevo chassis. You will certainly be able to find a UK or US supplier with a bit of digging.

Apple is better at scaling because it has tighter control over what software it allows but for me that's scant consolation. Also, I would advise against a 13" screen unless portability is the most important factor. I compared 4k on 13" vs 15" and the ease of use, particuarly readability and eye strain, was noticeable after only a short while.
My problem with Mac is I am too invested in PC software & useability to make the change. Macs are prettier and have many virtues but for me to change now it'd be time, money and hassle I'd rather not waste. You can get much more powerful PC laptops too. I have always shied away from a mac purchase because it'd be with my "ooh pretty" heart and not my head. Do you really want to get all new software, redo all presentations, set everything up again etc. when you can just get a decent laptop for considerably less money?
Finally, don't underestimate the performance a proper GPU will make, especially in larger files, rendering large LR catalogues or photo merging. It doesn't need to be a pro-spec gaming machine to have a dedicated video card and the differences is enormous - I had direct experience with this, my wife's laptop and my old one had identical CPUs but I had a gaming card in mine too. The difference was astonishing, and that's with a 5 year old video card. With a current gen one I'm looking forward to testing it with some massive files soon.
Remember not to skimp on the RAM, get 16gb minimum. But make sure that the CPU you choose can address the full set of RAM, some lower end CPUs can only address 4gb or 8gb.
