Love Pyramid's stainless steel tile idea. Or, a simple, painted glass backsplash.

Painted glass backsplash in your accent colour will be beautiful. You can take it above the cabinets into the archway. Very easy to keep clean.

A full glass backsplash would be pretty fantastic!

white subway tile

I have similar cabinets and pulls as well as stainless appliances. We went with glass tiles. We picked a light color that went with our cambria quartz countertops. I think with the sark cabinets it us best to go light with the backsplash. I am sure you will get many suggestions to use subway tiles. To me, they make me think im standing on a dingy subway platform!

Mixes of slate and small square glass tiles. If you're going to do something with the arch take advantage of it with colourful glass tiles. Maybe put a pot light in the middle of the arch to set it off. OR put rope lights behind your crown moulding so that it is unseen from standing in the kitchen. That would be really cool on colourful glass tile.

I would go for some contrast against the stainless with this quilted copper;)
