It's not the wall......
You have no depth in your palette. No texture, and you seem to be both warm and cool ( the carpet is gray ? )
The photos belong in another room. Your master bedroom.. a hallway passage.
Coffee table is an opportunity - it's the wrong size for the sectional. Maybe a large round, and a bit darker tone in wood.
The best before you worry on the wall? Would be a nice wood floor, and a decorative area rug.
As for now? The console under tv looks too small, and the chair......needs a hit of color.
Pale rooms need a lot of texture, some contrast... and variation in materials. Or they go a bit flat: )
