The # after RGB/8 means that the image has no embedded profile. It is "untagged".
When you export, make sure to check both Convert to sRGB and Embed color profile.
When you open an untagged image in Photoshop, and choose not to assign a color profile to it, there is no color management, and the image will be displayed with wrong colors.
Because you seem to have a wide gamut monitor, the difference will be quite big, compared to the original.
