We numerically compute the inclusive photon production in ${\rm p}+{\rm p}$ collisions within the Color Glass Condensate framework as determined through the valence $qg\to q\gamma$ leading-order channel and the $gg \to q\bar{q}\gamma$ next-to-leading-order channel, respectively. We find the $gg\to q\bar{q}\gamma$ channel accounts for more than $90\%$ of the cross section at the center of mass energies of $\sqrt{s} = 7$ TeV and $13$ TeV. The obtained numerical results compare well with the ATLAS and CMS ${\rm p}+{\rm p}$ data for inclusive isolated photon production within the region where $x < 0.01$ in either of the colliding protons.
