Without knowing the stations involved, I interpreted it as meaning

Kingsland was not.

No, there are two different symbols. The wheelchair symbol indicates
that Dalston Junction has step-free access; The linked discs indicate
an interchange with another line - look at Shadwell or Kings Cross for
examples where interchange is at the same station, there are lots
more.

But does the lack of wheelchair symbol on the other line not indicate
that only the ELL station has wheelchair access?
