sRGB PhotoShop Vs Unreal

Dear good and kind people of colourspace sRGB IEC61966-2.1…

I’ve noticed a slight discrepancy in the colours of a png exported from Photoshop (colour profile sRGB) imported into Unreal as UserInnterfaceRGBA.
The colours are similar but slightly washed out. Yes, I’m aware that it may be gamma correction that’s causing it, but how do I fix it?

Using Legacy Gamma didn’t seem to do anything at all.
