You need to add more pictures and a floor plan to get help on this site. It looks like the penisula cuts the kitchen in half. Add the pictures as a comment here - don't start a new dilemma.

At this point, a top quality washable paint is the best solution.

You do not need art between the windows. The focus should be on the view, not the art. If you are having a problem with splashing on the paint, by all means do a backsplash, but you don't need it for looks. There's plenty of visual interest, you don't need to add stuff.

Frankly, I'd keep it as is. Or paint it. I don't particularly like the paint, but no paint is going to look good overshadowed by light from the window, so the paint might be really nice in real life, just not in that photo. I have a yellow kitchen.

I do wonder what the entire space looks like. Why wasn't the peninsula reorientated, windows raised so the kitchen sink is on that back wall....

we need to see tthe whole space to even understand what you had planned before any stuff was oredered or installed. Why is it that the range looks like it is in the corner I need pics of the whole room posted here in comments DO NOT start another post.

Inside Mount Roman Shades. Plain or patterned fabric depending on how this kitchen we cannot see appears.

I have a counter and sink in front of windows that came in too low. I simply held the cabinets away from the windows and created a "well " in the countertop to accommodate the windows.

Thank you all for the inputs. I really appreciated!

Paint the wall a dramatic color, add window shades, a stunning light over the counter and a beautiful Italian platter on the wall for decor!
