I had the same problem - the correct size blinds I bought were broken and had to return them and could only get a set that was 1 inch shorter 😠
Ended up moving the mounts slightly inward so the gaps were on the edges. The two smaller gaps on the sides were a lot less noticeable than the gap in the middle. Also ended up putting curtains up to cover the edge gaps, though it wasn’t strictly necessary. I keep them pulled to the side, and they’re purely decorative / to hide the edge gaps.
