To be entirely fair, the glass doors are terrible for refrigeration efficiency because the glass is far less insulated than the door with the screen is. It might actually save electricity by powering a screen that shows a picture of the product over a insulated door than just having a glass door.

This implementation looks ugly as heck of course but if there's a big enough energy efficiency gain I suppose it might be worth the trade off

You can make insulated glass doors fairly easily. Just sandwich a gas between layers of glass. Look at any modern window for an example.

Still not as insulating as a thick door with the manufacturer's choice of insulation material. Double/triple pane glass is far better than a single pane window but a window is still a window
