I dont want to come across as a toff or criticising Virgin, but i think the little touches like a wooden coat hanger makes a difference, since it is J class afterall. i've read plenty of trip reports to know that travellers who fly J or F class etc, notice small details such as coat hangers lol
as much as they notice whether the cutlery is plastic or metal, drinks are served in glassware or how fluffy the pillow is etc etc...
Anyway the metal skinny ones are like the silver ones you get from dry cleaners and i wouldn't even hang my shirts in those.
And if they can manage it in white, that would be nice, but i wouldnt want the white paint to rub off on the jackets though.
