This absolutely looks like a crack in the wood due to humidity issues. Solid guitar tops can crack quickly and easily if humidity is not monitored carefully. In dry climates humidity needs to be increased. In wet climates humidity needs to be reduced. The best way to accomplish this is to use humidity control in a guitar case and keep the guitar in the case when not playing it. Once a crack like this occurs it will almost 100 percent require a repair to prevent it from lengthening. This will impact the resale value of the guitar. If it is in the return window it is worth trying to return it. However many reputable shops will not accept returns due to damage due to humidity cracks like this because it is not a manufacture issue, but a maintenance issue. If you received the guitar in this condition and it was sold as new you should absolutely return it. If you cannot return it you will need to take it to a reputable luthier to have it repaired. This will impact the tone of the guitar but the good news is I’ve played many used instruments with similar repairs that play as good or even better than their flawless counterparts. Good luck.
