I know a way to detect Z26. I stumbled upon it while working with the
AtariVox. (The high score tiable in MGD should not show without an AtariVox
connected - works fine on the real hardware and in Stella, but it still
displays in Z26.)
lda #$00
sta SWCHA
ldx #$ff
stx SWACNT
sta SWACNT
lda SWCHA
beq z26_detected
That's not exactly what I have in my code, but if I understand correctly why
it happens that should do the trick.

Yes.
