The drivers look like originals. I've never seen a fake one with green case, but I haven't seen every fake transistor in the world.
Regarding the specs, they also look OK for a driver transistor.
Anyway, as said in many posts, the transistor model shouldn't have such an impact in performance to make a night-day difference. I've fixed amplifiers with "lower specs" transistors (as fitting cheap TIP41-42 and BD139-140 inside a Sansui amplifier with burned outputs and drivers), and the amplifier sounds as good as the original (at least, a listening test can't tell the difference, perhaps THD or some laboratory test are not as good as the original, but you can't hear anything wrong with the amp).
I'd ask for the square wave tests before keep swapping parts hoping they will "fix" some issue by some magic. If something is not OK in the amp, all the transistors you fit will reproduce the same fail, they will "sound" the same.
