First of all, forget about using Chrome for viewing photos on that MacBook. It has a wide-gamut screen, and Chrome's colour management has been broken for a year or more on Mac.
Safari's scaling is controlled in two places. First of all, the web site can specify it. In conjunction with a @media query, you choose a different scaling factor or pixel width, such that you trick Safari into not upscaling images as it normally does on retina screens (it does that to preserve the relative sizes of text and images). The trick is reasonably well known, I use it in my own galleries, and it makes a difference on my iPad.
After this stage, the user can set a "zoom" themselves via the View menu. Choose View | Actual Size menu item (COMMAND 0) to turn this off (you want it greyed out).
Modern websites use "responsive design", which means they instruct the browser to resize elements like images rather than selecting different sizes on the server. So your quest for 1:1 is doomed to failure: increasingly, there is no such thing.
Safari uses the GPU to do tbis scaling and it is excellent on my Mac Pro. MacBooks do however come with a battery-saving feature in which they can turn off the main GPU and use the "integrated" one. Maybe Safari has to do it less well on that - you should make sure the GPU is turned on in Settings.
It might also be that what you're seeing is oversharpening on your HP laptop. There's a wrong way to scale images which results in that. On Mac, Safari doesn't use this wrong method, so it will not sharpen images that really are soft.
This site, both the desktop and iPad-specific version, looks great on my iPad Pro.
