Do you also see the difference or am I tripping?

The material of the container can effect the flavor of the contents.
Just like whiskey gets flavor from the barrels it ages in, coke alters its flavor depending on what container it’s stored in.
Aluminum cans have a polymer lining, and plastic bottles are made of plastic. This can affect the flavor of the coke.
Plastic bottles are also sometimes exposed to sunlight while being stored which can also affect the flavor.
Glass bottles don’t effect the flavor the same way.
Fountain coke at a restaurant on the other hand tastes quite different. This is because the coke in bottles and cans is carbonated with carbonic acid where-as the soda fountain carbonates water with CO2 directly and mixing it with the concentrate on demand.
The mix from fountains is often also off, so you might get a more watery product from the fountain, or because the ice it’s served with melted.
This is why canned coke tends to have a more bitter flavor, while fountains tend to be sweeter or watery.
