The choice beside cream upholstery and walnut
Cream upholstery and walnut can restrain the surrounding palette, leaving the blue-green wall as the room's main color.
Set up both candidates with cream upholstery and walnut. Use equal-sized boards with the intended finishes and place them in the same orientation. Do not put one directly beside a window and leave the other in shadow. A difference that follows the position rather than the board is a lighting observation, not evidence that the formula changed.
What the comparison can—and cannot—settle
The alternative Stardew has an LRV of 43.
Compare it to a less green blue before choosing accessories; let the paint establish the direction. Assess Moody Blue and Debonair alone as well as side by side. The unchosen board will not remain in the finished room, and a preference created only by that neighbor may not survive its removal. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
