It looks grand. I had to zoom in to see the gaps at each side which centre it in the gap. You could, if you were minded to, get some wood ‘trim’ and fill the gaps but matching the colour would be a huge nightmare. Trim pieces are available in a variety of profiles and easy to work with (Stanley knife will cut them) but the colour - that could prove the biggest obstacle. Any trim I’ve bought or seen is white wood and grained to some extent.
TLDR - Looks grand - leave it alone - good job! -
Ikea and other kitchen places do a long strip 3m of sticky back infinite edge. Get them in a few colours. Very good for disguising small gaps that aren't easy to scribe or make a blank for. One side sticks to your furniture on the vertical face inside the gap, the other is a 5 to 20mm bit of silicon that just nestles against the wall. Used them a few times to good effect
My walls (and house Tbf) are all over the shop, can we call 2cm a shadow gap?
