The picture from BUR-LJU was probably taken at least a month ago? Because that is an "old" C class meal. They do not serve the round "Foodmaker" meals anymore (or at least, not on my last 6 or so flights).
What I did get were meals in the style of the other pictures. On a MUC-BRU (shorter, late night) it was a selection of desserts. On BRU<>BCN flights I have had several different salads.

Overall, I think it's an improvement. (I didn't even look at the "Foodmaker" boxes anymore in the end.)
Although the meals are not designed to give you any "Heimat" or other culinary experiences, I'm glad they made the change.

On a side note: on service itself SN scores higher than LH, IMHO.
