At the moment I'm just Googling for various images of keyboards and what people have, but of course different lighting affects how they look so it's hard to gauge, plus it's not always clear if they're using Varmilo or a custom set. I need UK ISO and either Cherry profile or Varmilo's own (which I understand is very close to Cherry profile), so my options are more limited.
I suggest watching video reviews, you get a better idea. For pictures one can use the best possible light, usually natural light, so video reviews recorded indoors can give you a more accurate and realistic sneak peek.
About the ISO layout I wouldn't say limited since they
already have it. I was about to purchase UK layout myself before Google Images showed me
this !
