Civilian Piper's tartan

I found it, it's the 2018 George Sherriff Memorial

Here's the same tartan being worn in the 2017 competition (don't know if it's the same guy)

In any case, isn't this "78th Fraser Highlanders Pipe Band" tartan another Black Watch variant?

The green left as is, the black changed to blue, the blue changed to orange?

The difference being that the double-track motif occurring at the edges of the alternating orange squares has been reduced to a single line at each edge.
