It must depend what you cook. I don't do fried, spitty type dishes and the grout around the largish tiles in my now 10 year old kitchen is as good as new. I rubbed car wax into the freshly laid grout lines, same as I did in the bathroom. It also depends on how much light bounces around your kitchen, glass being so reflective shows up smears with light on it. Just above the kettle in the first photo is a good example. Each to their own, I'm a non-glass girl whenever I can get away with it.

Sorry Azza I don't have access to a full strength picture of Grand Piano....but why don't you paint up a swatch of Natural white from a sample pot (if you are near Gordon Park, I may even have a sample pot under my house still that I could give you as I have used Natural white elsewhere in my house. Also get a sample of your benchtop colour and cupboard colour and take it done to focus glass designs...and check out the colour both indoors and outdoors to see how they look in extreme of lights (because the lighter colours do vary depending on the light)....If you rang focus design beforehand and explained that one of their previous customers had recommended them on houzz website but that you were locked into the supplier based on who was building the house and would they mind if you just look at the Grand Piano colour in their showroom.......I found them so helpful, I think that they wouldn't mind you popping in to check out a couple of colours in their showroom. It is just a small family business....but had excellent customer service. They tell you whether the colour will achieve the look you are going for or not and that sort of advice is priceless ....the colour I initially wanted to use would have looked awful in my kitchen...

We had a guy who printed posters print the photo and stick it on the glass for us (to make sure there were no air bubbles). He delivered it to the glazier who was installing the splashback. There was so much interest as it sat in the showroom, the glazier then started offering glass with pictures actually printed onto them... If your wall was smooth, you could put the 'poster' print onto ther wall as another option.

Your kitchen is small and already quite busy. I would make it as simple and clean as possible. You can't beat ceramic tiles for cost, durability and ease of installation. Have a look at Johnson's Spectrum range to see if you can match the green. https://www.johnsontiles.com.au/product/spectrum/?utm_campaign=1602072422&utm_source=google&utm_medium=cpc&utm_content=304640004469&utm_term=&adgroupid=61761480198&gclid=CjwKCAjw_YPnBRBREiwAIP6TJ0idAicM8vfEevC-WrwRVNmbtUPHfDAjvNpkaOIo0hzN0dwMw9u1rxoC0VkQAvD_BwE You will get a neater finish with ceramic tiles than you will with trying to work with DIY stainless steel, particularly around the edges. There are lots of online resources to show how easy it is to lay smaller ceramic tiles. Leave the large format porcelain tiles to the professionals. Best of luck, Dr Retro of Dr Retro House Calls
