Found this on line.

Landlocked salmon have brown, green or blue backs with many small black spots. The sides are silvery and the dorsal fin also has large black spots. During the spawning season, the colouring becomes more bronze and the males develop red spots on the body.

If I had to guess I would still say with the position of the mouth relative to the eye and dots above the lateral line, this is a young male LL in spawning colors. If you look close, there are some faint black markings and the tail looks slightly forked as opposed to square.

I'd still send it to F&G for their opinion.
